Abstract

The present invention provides a method for preparing a graphene-like molybdenum disulfide-graphene composite material by reducing carbohydrate organic carbon. The method is as follows: 1, adding molybdenum disulfide powder into an intercalation solution for intercalation reaction, and filtering and drying after the reaction is complete to obtain intercalation molybdenum disulfide powder; 2, mixing the intercalation molybdenum disulfide powder obtained by the step 1 with the carbohydrate organic carbon and water in the proportion of intercalation molybdenum disulfide powder to carbohydrate organic carbon to water of 2g: (2-12) g: (20-120) g, stirring evenly, drying and grinding to obtain precursor powder; and 3, performing reduction reaction of the precursor powder under a protective gas, after the reaction is complete, cooling, and taking a reaction product for grinding to obtain the graphene-like molybdenum disulfide-graphene composite material. Through combination of intercalation reduction synthesizing of graphene-like molybdenum disulfide and synthesizing of graphene, the stripping of intercalation molybdenum disulfide and the production of graphene are completed in one step.

Description

technical field [0001] The invention belongs to the field of novel two-dimensional materials, and relates to a graphene-like molybdenum disulfide composite material, in particular to a method for preparing a graphene-like molybdenum disulfide-graphene composite material by reducing carbohydrate organic carbon. Background technique [0002] Graphene-like MoS2 composed of few layers of MoS2 is a new two-dimensional (2D) layered compound with graphene-like structure and properties. In recent years, it has become a new research hotspot due to its unique physical and chemical properties. Graphene-like molybdenum disulfide is a two-dimensional crystal material with a "sandwich sandwich" layered structure composed of hexagonal multi-layer molybdenum disulfide. The single-layer molybdenum disulfide is composed of three atomic layers, and the middle layer is molybdenum The atomic layer, the upper and lower layers are sulfur atomic layers, the molybdenum atomic layer is sandwiched by...
