Influence of the Cuprous Oxide's Morphology and Particle Degree on Photocatalytic Property

ZHAO Bin1,2,3,XIE Bin1,3(1.School of Material and Chemical Engineering,Sichuan University of Science & Engineering,Zigong 643000,China; 2.Key Laboratory of Green Catalysis of Sichuan Institute of High Education,Zigong 643000,China; 3.Institute of Functionalized Materials,Sichuan University of Science & Engineering,Zigong 643000,China)  
The cuprous oxide particles were obtained through the different preparation methods,its morphology is spherical,cube,octagonal and petals form,and characterized by XRD and SEM.The effects of the different morphology cuprous oxide on the photocatalytic property in the treatment of chromium(VI)-containing water was researched,the results show that the photocatalytic property of petals form cuprous oxide is the worst,and spherical is the best,the photocatalytic property of spherical cuprous oxide is relationship to the particle degree,the smaller particle size,the photocatalytic property is higher.
