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-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H2O2的用量在5 mL/30mL,亚甲基蓝的初始浓度为10 mg/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。

Abstract: Cu2O powders and TiO2-Cu2O composite powders were prepared by chemical deposition method. With prepared Cu2O nanoparticles as photocatalyst,photocatalytic oxidation degradation of methylene blue solution was explored. The effects of dosage of H2O2,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 H2O2 was 5mL in 30mL methylene blue solution and the initial concentration of methylene blue was 10mg / L,and the catalytic efficiency of TiO2-Cu2O composite powders was much higher than that of Cu2O.

Key words: cuprous oxide nanoparticles, photocatalytic degradation, composite powders, methylene blue
