英文摘要：

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 activity toward methyl orange degradation. The morphology and photocatalytic activity were investigated by adjusting Cu~（2＋）/ Zn~（2＋）ratio. Nearly 77. 5% of methyl orange was photodegradated over Cu2O / ZnO photocatalyst after5. 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.
