Description

Technical field

[0001] The invention belongs to the field of transition metal chalcogenides-carbon nanomaterials, and particularly relates to a method for preparing a molybdenum sulfide / graphene-graphene nanobelt aerogel composite material. Background technique

[0002] Carbon aerogel is a typical three-dimensional network structure, with low density, high porosity, large specific surface area, adjustable pore structure, good stability, and high conductivity. It is widely used as adsorption material, catalyst carrier and various electrodes The substrate of active materials is one of the most promising new materials in the future. According to the source of the matrix, carbon aerogels can generally be divided into organic-based carbon aerogels, graphene or carbon nanotube-based carbon aerogels, and biomass-based carbon aerogels.

[0003] Graphene is a single layer of graphite composed of sp2 carbon atoms arranged in a hexagonal direction. It has high internal carrier mobility (2000...
