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.
