Hydrothermal preparation of ZnO-reduced graphene oxide hybrid with high performance in photocatalytic degradation

► The one step hydrothermal method with ammonia used in this manuscript can reduce graphene oxide (GO) and anchor ZnO nanostuctures to reduced graphene oxide (RGO) sheets synchronously. ► The morphology of ZnO in ZnO-RGO can be changed by adjusting mass ratio between Zn(NO3)2·6H2O and GO used for preparation of ZnO-RGO. ► The ZnO-RGO can hinder the recombination of photo electrons and holes to enhance the photocatalytic degradation of methylene blue.
