Abstract

The invention relates to a preparation method of a three-dimensional carbon-boron nitride nanometer material. The preparation method adopts a three-step synthesis method, comprising the following steps: step 1, preparation of precursor colloid of diboron trioxide triethanolamine through thermosynthesis of solvent; step 2, preparation of precursor powder of melamine hypoboric acid through synthesis by a hydrothermal method; step 3, mixing of the precursor obtained in step 1 with the precursor obtained in step 2, uniform grinding and high temperature pyrolysis under reaction atmosphere, so as to obtain the three-dimensional carbon-boron nitride nanometer material with high specific surface area and uniform morphological structure. The preparation method has the advantages of low cost, high yield, no pollution, strong application and the like, and a novel three-dimensional carbon-boron nitride nanometer material with high specific surface area, high quality, high purity and high performances of both carbon and boron nitride, which can not be obtained by the existing method, can be obtained by the preparation method disclosed by the invention.
