Synthesis and Visibie-light Photocatalysis of Graphene/MoS2 Composites
Abstract:MoS2 is a new type of semiconductor material with high carrier mobility and high specific surface area. Based on many advantages, Graphene material has excellent electrical and mechanical properties, and it has important research value in optoelectronic devices and other fields. The construction and photocatalytic properties of Graphene/MoS2 composites were studied. The main research contents are as follows: Graphene/MoS2 composites were successfully prepared by hydrothermal method. The photocatalytic activity of Graphene/MoS2 composite was studied by controlling methylene blue degradation. The experimental results show that in the visible light conditions, methylene blue dye simulated pollutants, Graphene/MoS2 composite compared with the single MoS2 material has a better photocatalytic degradation efficiency, which photocatalytic degradation rate is up to 76.6% in 180min, far higher than MoS2 material which is 38.6%. The results show that Graphene/MoS2 composites exhibit superior photocatalytic properties in the decomposition of pollutants.
