摘　　要：采用溶液法,以五水硫酸铜为铜源,葡萄糖为还原剂,通过调节碱溶液用量,制备了多种形貌的微米Cu_2O材料,实现了正方体、球形和二十四面体形貌Cu_2O微米结构的可控合成,其结构、形貌和性能经UV-Vis,SEM,TEM和XRD表征。研究了三种不同形貌的微米Cu_2O对亚甲基蓝在可见光下降解反应的光催化性能。结果表明:二十四面体微米Cu_2O的光催化活性优于正方体和球形,降解率为97.72%。Three morphologies of cube, sphere and tetrahexahedron of pure Cu20 powder were suc- cessfully synthesized by a liquid phase method using copper sulfate pentabydrate as a copper source and glucose as a reducer. The effect of the volume of alkaline solution on morphology of Cu2O was studied. The structures, morphology and photocatalytic properties were characterized by UV-Vis spec- troscopy, SEM, TEM and XRD . The tetrahexahedron Cu20 exhibited better photoeatalytic activities than Cu20 in the other morphologies, and the decomposition effficiency＇was 97, 72%.
