中文摘要：

采用乙二醇为溶剂，成功合成了耦合系统Cu2O／Bi2MoO6，分别采用X射线衍射（XRD）、拉曼光谱（Raman）、X射线光电子能谱分析（XPS）和透射电子显微镜（TEM）进行表征．样品的光催化活性通过在可见光下降解结晶紫来获得．结果表明，当Cu与Mo摩尔比为0．08，Cu2O／Bi2MoO6展示出最高的光催化性能，仅在100Min结晶紫的降解率达到95．6％．同时，研究了耦合系统中Cu2O的量对其光催化活性的影响，并提出了合理的反应机制．

英文摘要：

A coupled system of Cu2O/Bi2MoO6 with enhanced visible-light photocatalytic activity was successfully synthesized using ethylene glycol （EG） as a solvent. The as- synthesized samples were characterized via X-ray power diffraction （XRD）, Raman spectrum, transmission electron microscopy （TEM）, X-ray photoelectron spectroscopy （XPS） and UV-Vis diffuse reflection spectrum （DRS） in detail. The photocatalytic activities of the synthesized samples were evaluated by monitoring the degradation of crystal violet solution under visible light. As a result, the obtained Cu20/Bi2MoO6 with the mole ratio of Cu/Mo 0.08 exhibited the excellent visible-light-driven photocatalytie performance, and the degradation ratio of crystal violet could reach 95.6% within 100 min. The effects of the amount of cuprous oxide on the catalytic activity of Cu20/Bi2 MoO6 were investigated. The possible reaction mechanism of this system was proposed.
