摘　　要：以Cu(CH3COO)2·H2O为原料,PVP(聚乙烯吡咯烷酮)和NaOH为添加剂,葡萄糖为还原剂,通过液相法在70℃下一步合成纳米Cu2O开口空心球.采用XRD、SEM、BET和紫外-可见分光光度法等手段对所制备的纳米Cu2O开口空心球进行表征.实验发现,PVP及洗涤水温对开口空心球结构的形成起关键性作用.由于此Cu2O样品的特殊形貌,其对有机染料活性艳红(X-3B)有较高的光催化活性,在1 h内降解活性艳红的效率高达98.26%.Cu2O hollow-opened nanospheres have been successfully prepared at a relative low temperature liquid phase method using Cu（CH3COO）2 · H2O as the starting materials and glucose as a reducing agent. The structure of cuprous oxide nanospheres was characterized by XRD, SEM, BET and UV-vis spectrophotometer. Further control experiments were also carried out to investigate the factors that impact the morphology and size of the products. The peculiar morphology implies that the cuprous oxide hollow-opened nanospheres possess a excellent photocatalytic activity. The degradation efficiency of Dye Brillant Red under visible light can be up to 98. 26 %.
