Effect of annealing temperature on the photocatalytic performance of ZnO@MoS₂ composite materials

Abstract

In this work, we report the ZnO@MoS2 composite materials prepared by a hydrothermal method, and the effect of annealing temperature on the photocatalytic performance of ZnO@MoS2 composite materials. It is found that annealing temperature plays an important role in the formation of MoS2 surface morphology, resulting in the dense films and a reduction of nanostructure nummber and active sites by enhancing temperature. Furthermore, ZnO@MoS2 composite materials annealed at 50 oC possess a higher photocatalytic degradation efficiency of 62.88% on methylene blue solution compared with ZnO materials or other samples.
