为探究一种绿色环保、操作简单、反应条件温和的特殊形貌结构Cu_2O合成法,采用液—液界面反应成功制备了多孔立方Cu_2O自组装纳米膜.探究了不同反应条件对样品形貌结构的影响,用X射线衍射分析仪、扫描电子显微镜对该膜进行表征,研究了其在不同吸附条件对甲酚红的吸附效果.结果表明:当CuCl_2浓度较低时产物为规则的立方结构,随着浓度的升高,立方结构会受到破坏并逐渐向球形转变,温度过高时膜的致密度会遭到破坏;水相pH值越高,立方结构的孔隙率越低,油相试剂则对样品形貌和孔隙率都有影响;当反应体系为正丁醇—水、CuCl_2浓度为50 mmol /L、水相pH = 10.00时,产物是边长200 ~ 500 nm的多孔立方体均...

In order to explore a Cu2O synthesis method which is environmental friendly, sinnple to operate, and only needs mild reaction conditions, self-assembled cubic nano-porous Cu2O film was prepared by liquid-liquid interfacial reaction. The relationship between reaction conditions and the structure and morphology of Cu2O film was investigated by analyzing the samples under different reaction conditions with XRD and SEM. The capacity of the sample to adsorb cresol red was studied under different adsorption conditions. Result shows that structure and...
