摘要：
Nickel catalyst supported on honeycomb cinder (Ni/HC) was prepared by a homogeneous precipitation method. The catalyst was applied to produce hydrogen-rich combustible gas by catalytic pyrolysis of soybean straw and plastic (PE) mixture. The straw and plastic materials were analyzed by elemental analysis and industrial analysis. The support and catalyst were characterized by X-ray fluorescence (XRF), X-ray diffraction (XRD), scanning electron microscopy (SEM), and N2 adsorption-desorption isotherm (BET). The analysis showed that NiO was well loaded on the surface of honeycomb coal slag carrier. The effects of Ni loading, pyrolysis temperature, holding time, and calcination temperature on the experimental results were studied. The results showed that the preparation of the catalyst was feasible and that it had a good catalytic effect. When Ni loading was 15 wt.%, catalytic pyrolysis temperature was 700 °C, holding time was 20 min, and calcination temperature of catalyst was 400 °C, H2 concentration increased from 20.6 to 52.8 vol.%, and while H2 yield was 302 mL/g, CH4 concentration decreased from 51.1 to 22.6 Vol.% and CO concentration increased from 10.8 to 17.8 vol.%. After the catalyst was regenerated 6 times, the H2 concentration still reached 40 vol.% and the combustible gas concentration was still above 80 vol.%. The catalyst still had good catalytic activity. © 2021, North Carolina State University. All rights reserved.

摘要：
A novel optofluidic photocatalytic fuel cell consisted of a Cu2O photocathode and a BiVO4 photoanode for efficient electricity generation from wastewater treatment. The dual-photoelectrodes design can greatly improve the separation efficiency of the photoexcited charge. Notably, the photoelectrodes were shoulder-to-shoulder placed in a microchamber, not only providing easy fabrication but also offering a large contact area between electrolyte and photoelectrodes. Additionally, the reduced inherent ohmic loss of as-established optofluidic PFC increased the maximum theoretic power density by ~60%. The photoelectricity conversion in using glucose as model organic waste has been entirely recorded under 1 sun illumination. The open-circuit voltage and short-circuit photocurrent were 0.463 V and 0.113 mA cm-2, respectively, which were ~2.5 times higher than that of the traditional large-dimension PFC. The PFC proposed in this study opened up a new insight into developing an efficient PFC system for pollutant treatment and electricity generation. © 2020 Elsevier Inc.

摘要：
A LaAlO3 carrier was prepared via the sol-gel method, and a Ni/LaAlO3 catalyst was prepared via the homogeneous precipitation method; this catalyst was used for the catalytic pyrolysis of soybean straw for syngas (H2 + CO) production. The analysis of the raw materials (straw) was performed via elemental analysis and industrial analysis. The support and catalyst were characterized and analyzed by X-ray fluorescence spectroscopy, thermogravimetric analysis, X-ray diffraction, scanning electron microscopy, and N2 adsorption-desorption isotherms. The results illustrated that the NiO was uniformly loaded on the LaAlO3 surface. Furthermore, the effects of the Ni loading amount, pyrolysis temperature, holding time, and calcination temperature on the performance of the catalyst were studied. The results showed that the catalyst had the highest increase in production and concentration of H2 and CO when the Ni loading was 10 wt%, the calcination temperature was 500 °C, the reaction temperature was 800 °C, and the holding time was 20 min. Compared with the pyrolysis of straw without a catalyst, the yield of H2 and CO increased from 85 mL/g and 125 mL/g to 238.5 mL/g and 255 mL/g, respectively, and the concentration of H2 and CO increased from 23.5 vol% and 29.4 vol% to 43.1 vol% and 41.9 vol%, respectively. © 2020, North Carolina State University.

摘要：
An in-situ electro-Fenton system with double anodes and Pd/CeO2 catalyst, which is powered by photovoltaic energy, is constructed. As the process only needs to replace the catalyst and iron anode regularly, and H2O2 and Fe2+ are in-situ generated and continuously added, it not only greatly reduces labor intensity and safety risks but also saves reagents and run cost. In this paper, the process is used to remove sulfadiazine (SDZ), one of the sulfonamides, from the simulated livestock and poultry breeding wastewater containing antibiotics. The results show that the features of Pd/CeO2 catalyst are successfully characterized by XRD, TEM and XPS. Under the conditions of only catalyst, only power, power and catalyst and electro-Fenton (EF), sulfadiazine removal efficiency for EF is the highest and 96.5% in 150 min. In addition, sulfadiazine removal follows a pseudo-first-order kinetic model. Current density of 15 mA/cm2, pH of 3, catalyst dosage of 0.1 g and current ratio of 0.15:0.02 is determined as the optimal conditions. Whether irradiation intensity is very weak or fluctuates broadly, sulfadiazine removal efficiency is all very high and more than 95% in 150 min. TOC results indicate that the mineralization extent of sulfadiazine is very high and HPLC results show that the adopted process is highly effective. Based on the UHPLC/MS results, seven intermediate products are detected and the removal mechanisms of sulfadiazine are proposed. The in-situ electro-Fenton process powered by photovoltaic energy is feasible. © 2020 Elsevier B.V.

摘要：
The co-gasification of wheat straw and wet sewage sludge for hydrogen-rich gas production was investigated in a fixed bed reactor with corn stalk char (CSC)-supported catalysts. The Ni/CSC, Ni-Fe/CSC, and Ni-Fe-La/CSC catalysts were characterized via ultimate analysis, X-ray fluorescence. thermogravimetric, X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy. Brunauer-Emmett-Teller, and Fourier transform infrared spectroscopy analyses. A series of experiments were performed to explore the effects of reactor temperature, catalyst type, moisture content of wet sludge, and catalyst recycling performance on the composition and yield of gasification gases. The experiments demonstrated that the nickel-iron alloy (Fe0.64Ni0.36) was detected in the Ni-Fe-La/CSC catalyst, and the Ni-Fe-La/CSC catalyst showed much higher hydrogen production compared with the Ni/CSC and Ni-Fe/CSC catalysts. Furthermore. La203 effectively maintained the catalytic performance of the catalyst by relieving carbon deposition. Compared with non-catalyst biomass gasification, H2 yield increased from 3.80 mol/kg to 11.96 mol/kg using Ni-Fe-La/CSC catalyst at 600 °C. The newly developed tri-metallic Ni-Fe-La/CSC catalyst exhibited high catalytic activity for biomass gasification at low temperature. © 2020, North Carolina State University.

摘要：
The wide application of zero-valent iron (ZVI) technology was limited by its slow electron transfer rate because of the dense iron oxide on ZVI surface. In this study, we reported a method to improve the performance of ZVI by ball-milling ZVI with ethylenediaminetetraacetic acid (ZVI-EDTA). The pretreatment of ZVI with EDTA provided acidic sites for ZVI surface corrosion, and thus increased the amount of surface Fe0 from 7.23% to 30.12%. Because of the promoted surface Fe0 amount, the corrosion potential of ZVI-EDTA shifted from −0.66 V to −0.75 V, and the concentration of dissolved ferrous ions and total ions increased, resulting in high efficiency in Cr(VI) removal. This study provides an effective method for enhancing the reactivity of commercial ZVI powder, which could contribute to the wide application of ZVI technology, especially in heavy metal remediation. © 2020

摘要：
At room temperature and atmospheric pressure, water electrolysis and Pd/MWCNTs catalyst are used to investigate the feasibility of in-situ synthesizing hydrogen peroxide in a safe way. Meantime, the ordinary Ti/β-PbO2 anode and graphite cathode are adopted to construct the water electrolysis system. During experiments, the features of Pd/MWCNTs catalyst are characterized by transmission electron microscope/energy dispersive spectrometer, X-ray diffraction and X-ray photoelectron spectroscopy. The effect of pH, current density, catalyst dosage, interelectrode distance, agitation speed and different cations on H2 O2 concentration is studied. Energy consumption for different current density is analyzed, too. The results show that H2 O2 concentration for the optimal conditions, namely current density of 20 mA/cm2, pH of 3, catalyst dosage of 0.5 g, interelectrode distance of 20 mm and agitation speed of 460 rpm, can attain to about 28 mg/L in 90 min. Additionally, under the above conditions, H2 O2 concentration for water including Mg2+ ion can rapidly get to about 36 mg/L in 30 min. Em increases from 213.0 to 368.8 kWh/kg when current density varying from 10 to 25 mA/cm2. However, for the lowest current density of 5 mA/cm2, its Em is 288.5 kWh/kg and is very high, too. The used process is feasible for in-situ synthesis of hydrogen peroxide. © 2020 Desalination Publications. All rights reserved.

摘要：
A Ni/Zr-MOF catalyst supported on Zr-metal organic framework (Zr-MOF) was prepared by a homogeneous precipitation method and was used in the co-gasification of wet sludge and straw. The Ni/Zr-MOF catalyst was characterized via thermogravimetric, X-ray diffraction, scanning electron microscopy, energy dispersive spectrometry, and Brunauer-Emmett-Teller analyses. The experimental results illustrated that the Zr-MOF crystals were an octahedral structure with a specific surface area of 806 m2/g, and had mesoporous structure. Nickel was uniformly dispersed on the surface of the catalyst, and most of the Ni/Zr-MOF crystals maintained an octahedral morphology. Compared with non-catalyst biomass gasification, the H2 yield increased from 0.39 mol/kg to 11.87 mol/kg using the Ni/Zr-MOF catalyst at 500 °C. After 10 instances of reuse, the H2 yield was still as high as 10.11 mol/kg. The Ni/Zr-MOF catalyst exhibited high catalytic activity and stability for biomass gasification at low-temperature. © 2020, North Carolina State University.

摘要：
Ni-xLa/Al2O3-MgO-sawdust char catalysts were prepared by modifying the Ni/Al2O3 catalyst from two aspects of support and active components. The effect of Al2O3, MgO, sawdust char molar ratio, and La content of catalysts on syngas (H2 + CO) production in the catalytic pyrolysis of rice straw was investigated in a horizontal fixed-bed quartz tube reactor. Furthermore, the stability of catalysts with the optimum catalytic performance was tested and compared with that of the Ni/Al2O3 catalysts. X-ray diffraction, X-ray fluorescence, field emission scanning electron microscopy, energy disperse X-ray, and Brunauer-Emmett-Teller analyses were applied to understand the physiochemical properties of the supports and catalysts. The study revealed that the supports were composed of many irregular flaky particles and thus formed many pores. Moreover, the addition of La decreased the particle size of NiAl2O4 and increased the active metal surface of the Ni/Al2O3-MgO-sawdust catalysts. When the molar ratio of Al2O3, MgO, and sawdust char was 1:1:1 and the La content was 10 wt% (dry weight basis), the catalysts presented the highest syngas concentration of 78.9 vol% and the most stable performance during the catalytic pyrolysis process. © 2020, North Carolina State University.

摘要：
Hierarchical β-Ni(OH)2 nanostructures composed of ultrathin nanosheets were synthesized via a hydrolytic process of nickel chloride. The obtained samples were characterized by X-ray diffraction, thermal gravimetric, scanning electron microscopy, transmission electron microscopy and X-ray photoelectron spectrometer. The corresponding results show that the Ni(OH)2 has a β-phase structure, and the hierarchical β-Ni(OH)2 nanostructures are made up of several cross-linked nanosheets, and the thickness of the nanosheets is only 9.3nm. The ultrathin nanosheets provide a very short diffusion channel for ion migration, which is beneficial to improve the electrochemical activity of the sample. The ultrathin β-Ni(OH)2 nanosheets aggregates have a specific capacitance of 1727 F/g at a current density of 1 A/g. Increasing the current density to 20 A/g, the specific capacitance can still maintain at 1235 F/g. Importantly, after 1000 charge–discharge cycles, the results show that the loss of the specific capacitance is only 1.6% at 1 A/g, and the loss is 27.9% at 20 A/g. The excellent performances of β-Ni(OH)2 nanostructures used as pseudocapacitors reveal the great potential of ultrathin nanosheets materials in energy storage. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.

摘要：
A new benzyls pendant-armed macrobicyclic heterbinuclear Cu(Ⅱ)-Ni(Ⅱ) complex has been obtained by template-directed synthesis and characterized by elemental analysis, IR spectra, electrospray mass spectra, and single crystal X-ray diffraction. The complex was bridged by two phenolic oxygens and an acetate radical, with the Cu(Ⅱ)-Ni(Ⅱ) distance of 2.9292(8) Å. The hydrolytic function, CT-DNA binding and antibacterial properties were also studied. The initial rate values for the hydrolysis of 4-nitophenylphosphate to 4-nitrophenolate by the Cu(Ⅱ)-Ni(Ⅱ) complex was 1.33 × 10−5 s−1, and 104 times faster than that the spontaneous hydrolysis of the phosphate monoester. The complex shows a better binding property to CT-DNA and the intrinsic binding constant is 1.29 × 105 M−1. The Stern-Volmer constant is 1.25 × 105 M−1. The viscosity increased obviously with the increase of complex concentration, the results showed that the complex bind to DNA through intercalation mode, which was in accordance with the absorption and emission spectral studies. The antibacterial activities against E.coli was also investigated using the Gentamycinas reference system. © 2019

摘要：
A catalyst loaded Ni-Fe using powder active carbon (PAC) and gamma-Al2O3 as the support was prepared for hydrogen-rich syngas production from rape straw pyrolysis in a two-stage fixed reactor. EDX (Energy dispersive X-ray spectroscopy), SEM (Scanning electron microscope) and N-2 isothermal adsorption desorption were used to characterize the catalysts. The results showed that the support of PAC-gamma Al2O3 was uniform with large specific surface area. The metals loaded on the support were well dispersed. The performance of Ni-Fe/PAC-gamma Al2O3 catalysts compared with single support catalyst NiO-Fe2O3/gamma Al2O3 (NFA) and NiO-Fe2O3/PAC (NFP) was studied. The results showed that the Ni-Fe/PAC-gamma Al2O3 catalysts showed a good catalytic activity which obviously enhanced the H-2 gas yield to 54.23 g/kg Rape straw and reduced the tar yield to 4.06 g/kg. Meanwhile, Ni-Fe/PAC-gamma Al2O3 catalysts had a stronger ability to prevent the deactivation to keep a longtime stability than the single carrier catalyst. (C) 2019 Elsevier Ltd.

摘要：
A new macrocyclic heterobinuclear Cu(II)-Zn(II) complex was synthesized and characterized by elemental analysis, FT-IR, ES-MS, and single-crystal X-ray diffraction. Five-coordinate geometry for the new complex is proposed. The copper…zinc distance bridged by two phenolic oxygens and a acetate ligand is 2.9508 Å. The phosphate ester hydrolysis activity and the DNA binding ability of the complex were studied. The results showed that the present complex has an efficient catalytic activity of phosphoester bond cleavage. The catalytic rate constant kcat for the hydrolysis of 4-nitrophenyl phosphate disodium salt hexahydrate (pNPP) by the synthesized complex is 2.69 × 10−4 s−1 and 105 times faster than the spontaneous hydrolysis of the phosphate monoester. The complex shows a good binding ability to calf thymus (CT-DNA) and the corresponding binding constant is 1.9 × 105 M−1. The linear Stern-Volmer quenching constant obtained by the fluorescent spectroscopic is 6.3 × 104 M−1. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.

摘要：
通过均匀沉淀法制备了以锆-金属有机骨架化合物(Zr-metal organic framework,Zr-MOF)为载体的Ni/Zr-MOF催化剂,并用于湿污泥和秸秆混合催化热解实验。采用元素分析、X射线荧光光谱(XRF) 、热重分析(TG) 、X射线衍射(XRD) 、扫描电镜(SEM)和N_2吸附-脱附等温(BET)对载体和催化剂进行表征分析,通过一系列实验来探讨热解温度、秸秆添加量和Ni负载量对于湿污泥和秸秆混合催化热解制备富氢合成气的影响。结果表明,Zr-MOF载体颗粒均匀呈八面体,比表面积高达805.93 m~2/g,平均孔径为20.14 nm,为介孔结构。Ni/Zr-MOF催化剂具有较高的热稳定性和催化活性。与不添加催化剂相比,使用Ni/Zr-MOF催化剂在500 ℃下热解,H_2的产量从0.39 mol/kg显著提高到12.65 mol/kg。随着热解温度的升高,催化剂出现团聚现象,同时在反复使用之后其表面产生了少量的积炭,导致催化剂催化活性逐渐降低。因此,Ni/Zr-MOF催化剂适用于生物质低温催化热解。

摘要：
Based on solidified floating organic drop microextraction (SFODME), a novel method was developed for the simultaneous speciation of inorganic arsenic (As(V)/As(III)) and antimony (Sb(V)/Sb(III)) by electrothermal vaporization inductively coupled plasma mass spectrometry (ETV-ICP-MS). Ammonium pyrroine-dithiocarbamate (APDC) was used as both a chelating reagent in SFODME and a chemical modifier in ETV. As(III)/Sb(III) could react with APDC to form complexes at pH 5.5, and the complexes were quantitatively extracted into organic phase of 1-dodecanol, whereas As(V)/Sb(V) remained as free species in the aqueous phase. As(III)/Sb(III) was directly determined by ETV-ICP-MS. Total As/Sb was determined by the same method after reducing As(V)/Sb(V) to As(III)/Sb(III). The assay of As(V)/Sb(V) was obtained by subtracting As(III)/Sb(III) from total As/Sb. The main factors affecting the separation and determination, including pH, amount of APDC, extraction time, stirring rate, sample solution volume and temperature program, were examined in detail. Under the optimized conditions, the detection limits were 0.18 pg mL−1 for As(III) and 0.37 pg mL−1 for Sb(III). The relative standard deviations for As(III) and Sb(III) were 4.7% and 5.9% (c=1.0 ng mL−1, n=9), respectively. This method was applied for the simultaneous speciation of inorganic arsenic and antimony in natural water samples and standard reference materials with satisfactory results. © 2019, Perkin - Elmer Corp.
