摘要:

以CuSO4和ZnCl2为原料, 采用温和的液相还原法制备得到Cu2O/ZnO微米结构高效光催化剂. 研究了不同[Cu2+]/[Zn2+]比条件下所得Cu2O/ZnO复合物的形貌和光催化活性. 通过5.5 h的光照, Cu2O/ZnO光催化剂对甲基橙染料的降解率为(77.5±0.1)%. 将多形貌Cu2O/ZnO复合物作为阳极, 铂片作为对电极, 中间注入甲基橙溶液, 组装“三明治”结构拟电池, 研究了复合物的光降解机制.

Abstract:

The cuprous oxide/zinc oxide(Cu2O/ZnO) microstructure were prepared by a mild solution strategy. The integration of polymorphic Cu2O with wurtzite ZnO is a facile approach of elevating photocatalytic activity toward methyl orange degradation. The morphology and photocatalytic activity were investigated by adjusting Cu2+/Zn2+ ratio. Nearly 77.5% of methyl orange was photodegradated over Cu2O/ZnO photocatalyst after 5.5 h light irradiation. The potential photodegradation mechanism was demonstrated by designing a pseudo cell comprised of polymorphic Cu2O/ZnO anode, Pt counter electrode and sandwiched methyl orange solution.

Key words: Photocatalyst, Polymorphology, Cu2O/ZnO microstructure, Methyl orange
