摘要

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 ac. tivity toward methyl orange degradation. The morphology and photocatalytic activity were investigated by adjus. ting 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.
