摘    要:采用化学沉积法制备Cu2O粉体,并且制备了TiO2-Cu2O复合粉体。以制备的纳米Cu2O为光催化剂,对亚甲基蓝溶液进行光催化氧化降解。通过紫外一可见分光光度计考察了H2O2的加入量、亚甲基蓝的初始浓度及复合样品对降解性能的影响。结果表明,当H202的用量在5mL/30mL,亚甲基蓝的初始浓度为10mg/L时降解效果最好;复合粉体的催化效率远高于Cu2O的光催化效率。

关 键 词:纳米Cu2O  光催化降解  复合粉体  亚甲基蓝

Abstract:Cu20 powders and TiO2-Cu20 composite powders were prepared by chemical deposi- tion method. With prepared Cu20 nanoparticles as photocatalyst, photocatalytic oxidation degrada- tion of methylene blue solution was explored. The effects of dosage of H202, the initial concentration of methylene blue and composite samples on the degradation performance were investigated with UV-visible spectrophotometer. The results showed that the degradation efficiency was the best when the amount of H202 was 5mL in 30mL methylene blue solution and the initial concentration of methy- lene blue was 10mg / L, and the catalytic efficiency of TiO2-Cu20 composite powders was much high- er than that of Cu20.
Keywords:cuprous oxide nanoparticles  photocatalytic degradation  composite powders  methylene blue
