Abstract

The invention provides a preparation method for a flower-like titanium nitride/carbon nitride/graphene composite nanomaterial. The method comprises the following steps of obtaining titanium nitride firstly, and then obtaining a flower-like composite under the action of a lysine template through a hydrothermal method, wherein the size of the flower-like structure is about 1.5 micron, the flower-like structure is formed by interlacing ultrathin nanosheets with the thickness of 17-23 nm with each other, the specific surface area of the material is 200-260 m<2>/g, so that the composite shows better characteristics when the composite is taken as an electrode material or a photocatalyst. The method has the advantages of simple technique, low cost, short period, friendly environment and the like and can be applicable to industrial mass production.

Description

technical field [0001] The invention belongs to the technical field of nanomaterial application, and in particular relates to a preparation method and application of a flower-shaped titanium nitride / carbon nitride / graphene composite nanomaterial. Background technique [0002] The study of nanomaterials is a frontier field in today's scientific research, and it is also a hot spot studied by many scientists all over the world. The magic and unknown aspects of nanomaterials have aroused people's widespread attention; the research and application of nanomaterials are currently hot spots and difficulties, and are also the focus of high-tech development.
