NOVELTY - Preparation of three-dimensional grid-shaped graphene material involves grinding and mixing a carbon source and a template agent uniformly, calcining at high temperature of 700-1100degrees Celsius for 2-8 hours under protective atmosphere, and washing the template agent. The template agent is a chloride salt and/or a carbonate of an alkali metal. USE - Preparation of three-dimensional grid-shaped graphene material. ADVANTAGE - The method removes the template easily, and provides three-dimensional grid-shaped graphene material without using strong acid, strong oxidant and aqueous or organic solvent by solid phase synthesis.
