摘要：
The PVP/Fe3O4/TBT composite nanofibers have been successfully fabricated via a facile electrospinning assisted sol-gel process, and magnetic TiO2 hollow nanofibers are obtained by the calcination process. The effects of TBT and Fe3O4 dosage on the morphologies and hollow structure of nanofibers are systematically investigated. Scanning electron microscopy (SEM) demonstrated that the magnetic TiO2 nanofibers had a hollow structure with the average diameter of 200 nm. XRD results exhibited that magnetic TiO2 hollow nanofibers with well crystallized anatase phase were obtained. Both the hollow structure and well crystallized anatase phase of TiO2 nanofibers play very important role in photocatalytic activity. Moreover, the magnetic test demonstrated TiO2 hollow nanofibers possessed an excellent magnetic responsiveness, which facilitated the separation of TiO2 hollow nanofibers.

摘要：
The acetylation of cellulose using sulfonated Amberlyst 15 as a new and reusable catalyst was investigated. Optimization of the acetylation process was carried out by variation in the amount of added catalyst, acetic acid, and acetic anhydride as well as the reaction conditions, which includes reaction time and reaction medium. Cellulose acetate, with a degree of substitution (DS) value of 2.38 and yield of 54.1%, was obtained under the optimized conditions and characterized using Fourier-transform infrared (FTIR) spectroscopy, thermogravimetric analysis-derivative thermogravimetry (TGA-DTG), and differential scanning calorimetry (DSC). The sulfonated polymer catalyst could be easily recovered by centrifugation after acetylation. Both the fresh and recovered catalysts were characterized by means of FTIR, TGA-DTG, DSC, and scanning electron microscopy (SEM), and the recovered catalyst could be successfully reused without further treatment. It was found that Amberlyst 15 possessed excellent catalytic stability, no significant changes in the DS values, and consistent yields of cellulose acetate observed over four reaction cycles. © 2014 Published by Elsevier Ltd.

摘要：
The hydrolysis of cellulose catalyzed by sulfonated poly(styrene-co- divinylbenzene) (SPS-DVB) was carried out in the ionic liquid 1-n-butyl-3-methylimidazolium bromide (BMIMBr), in which the reaction medium BMIMBr and sulfate polymer catalyst can be recovered. The influence of the amount of catalyst, water and ionic liquid, reaction conditions including reaction time and temperature was investigated in detail. The recovery of BMIMBr was performed based on using Aliquat 336 and naphthalene-2-boronic acid to extract the sugar derived from the hydrolysis of cellulose, and it was reused without further treatment. It was found that ionic liquid possessed excellent stability, and the conversion of cellulose almost kept constant during the recycles. The fresh and recovered sulfonated catalysts were characterized by means of TGA and IR, and the recovered catalyst was reused with/without treatment with acid. The catalytic activity almost kept constant in the case of regenerating by sulphuric acid prior to reuse, but a significant loss of activity was observed without regeneration. The results revealed that there may be an ion exchange process between the acidic sites of sulfonated catalyst and ionic liquid during the hydrolysis of cellulose. © 2013 Published by Elsevier B.V.

摘要：
Dimethyl carbonate (DMC) was synthesized from carbon dioxide, propylene epoxide (PO) and methanol. The catalytic performance of K2CO3, KI, rare earth oxides including CeO2, Y2O3, La2O3 and Yb2O3 was investigated. Acceptable conversion of PO but poor selectivity to DMC was obtained using K2CO3 or KI as the sole catalyst compared to that obtained in the presence of rare earth oxides. Significant improvement in the selectivity to DMC was obtained catalyzed by co-catalyst composed of K2CO3 and Yb2O3, and 42.4% selectivity to DMC, which is higher than that obtained using K2CO3 or Yb2O3 as the sole catalyst under the identical conditions, was obtained. The influence of the amount of PO was also investigated, and the results showed that the conversion of PO is dependent on its amount.

摘要：
Cellulose was isolated from rice straw by pretreatment with dilute alkaline and acid solutions successively, and it was further transferred into cellulose acetate in the presence of acetic anhydride and phosphotungstic acid (H 3PW12O40·6H2O). The removal of hemicellulose and lignin was affected by the concentration of KOH and the immersion time in acetic acid solution, and 83 wt.% content of cellulose in the treated rice straw was obtained after pretreatment with 4% KOH and immersion in acetic acid for 5 h. Phosphotungstic acid was found to be an effective catalyst for the acetylation of the cellulose derived from rice straw. The degree of substitution (DS) values revealed a significant effect for the solubility of cellulose acetate, and the acetone-soluble cellulose acetate with DS values around 2.2 can be obtained by changing the amount of phosphotungstic acid and the time of acetylation. Both the structure of cellulose separated from rice straw and cellulose acetate were confirmed by FTIR and XRD. © 2013 Elsevier Ltd. All rights reserved.

摘要：
Bimetallic aluminum(salen) complexes were prepared and used as catalyst for the synthesis of DPC from CO2 and phenol in the presence of carbon tetrachloride. The bimetallic complex derived from 3,5-ditert salicylaldehyde and 1,2-cyclohexanediamine revealed more excellent activity than that obtained in the presence of other complexes and the simple Lewis acid ZnCl2. The influence of the amount of complex and the reaction conditions including the pressure of CO2 and the reaction temperature was also investigated.

摘要：
Diphenyl carbonate (DPC) was synthesised from carbon dioxide, phenol, and carbon tetrachloride catalysed by the Lewis acid ZnCl2 with the addition of co-catalyst. It was found that common bases are not effective co-catalysts for the production of DPC, and only slight enhancement in the catalytic activity of ZnCl2 was observed in the presence of inorganic additives such as inorganic carbonates and quaternary ammonium salts. Although poor conversion of phenol and yield of DPC were obtained using ZnCl2 or trifluoromethanesulfonic acid (CF3SO3H) as the sole catalyst, the catalytic activity of ZnCl2 was significantly improved by the addition of a catalytic amount of CF3SO3H. CF 3SO3H has been proven to be an effective co-catalyst. The conversion of phenol and the yield of DPC were dependent on the amount of ZnCl2 and CF3SO3H, the reaction temperature, and the pressure of CO2. A possible reaction mechanism for the synthesis of DPC catalysed by the co-catalytic system including ZnCl2 and CF3SO3H was also proposed. © 2012 CSIRO.

摘要：
The catalytic pyrolysis of palm oil wastes for fuel gas production was experimentally investigated in a combined fixed bed reactor using the developed nano-NiO/γ-Al<inf>2</inf>O<inf>3</inf> catalyst. The results indicated that the nano-NiO/γ-Al<inf>2</inf>O<inf>3</inf> catalyst had greater activity for the cracking of tar in vapor and of hydrocarbons and a higher hydrogen yield than the commercial nickel-based catalyst in catalytic pyrolysis of palm oil wastes. Meanwhile, a series of experiments have been performed to explore the effects of temperature and biomass particle size on gas composition and gas yield. The experiments demonstrated that temperature was the most important factor in this process, higher temperature contributed to more hydrogen production and gas yield. It was also shown that a smaller particle was more favorable for gas quality and yield. ©2012 IEEE.

摘要：
A novel and facile wet-chemical method for synthesis of silver microwires was developed.The well-defined particles were prepared by adding an iron(Ⅱ) sulfate heptahydrate solution into a silver nitrate solution containing citric acid drop by drop at 50 °C.The resulting products were characterized by scanning electron microscopy and X-ray diffraction.It was found that the particles consisted of numerous silver microwires.The reaction temperature greatly affected the morphologies of the as-prepared particles.Both of the mean length and width of the silver microwires increased with the decrease of the concentration of silver nitrate.And the lower concentration was unfavorable for the formation of more silver microwires.Similar findings were also observed when the concentration of iron(Ⅱ) sulfate was decreased.The amount of citric acid also greatly affected the shape of the as-prepared particles.It was concluded that citric acid was the key role in the formation of silver microwires via the Oswald ripening mechanism.

Diphenyl carbonate (DPC) was synthesized from CO2 and phenol catalyzed by Lewis acids. Compressed CO2 was used as reactant and solvent. It was found that the conversion of phenol and the yield of DPC are dependent on the metal center of Lewis acids, and zinc halides have better catalytic performance than aluminum halides. The reaction of CO2 with phenol is sensitive to pressure, temperature, and reaction time, and it is improved using triethylamine as acid acceptor. A 31.7% DPC yield was obtained under optimized reaction conditions: 9 MPa at 100 °C for 3 h. © 2011 Elsevier B.V.

摘要：
A novel method for the direct synthesis of diphenyl carbonate (DPC) from carbon dioxide and phenol catalyzed by Lewis acid in the presence of methanol was developed. It was found that the simple Lewis acids are not effective for catalyzing the production of DPC, but (salen)Co(OAc) containing a quaternary phosphonium salt unit anchored on the ligand displayed excellent catalytic activity under mild conditions using dense carbon dioxide as reactant and solvent. A possible mechanism for the formation of DPC was proposed based on the GC-MS analysis and DFT calculation.
