▎ 摘　　要

NOVELTY - Activating two-dimensional nitrogen-doped graphene, comprises mixing melamine, ammonium chloride, and polyvinylpyrrolidone and calcining to obtain a black solid material, which is nitrogen-doped graphene, adding magnesium sulfate into the nitrogen-doped graphene for mixing, and placing the mixed material in a muffle furnace for calcination to obtain a black and white material, soaking the black and white material in a beaker containing distilled water and filtering to obtain a black solid material. USE - Method for activating two-dimensional nitrogen-doped graphene, which is useful in chemical material preparation. ADVANTAGE - The method uses magnesium sulfate as activating agent, using mild calcining temperature to activate the two-dimensional nitrogen doped graphene material, the activated material is not activated two- dimensional carbon material than the surface area is obviously improved, and the heteroatom doping amount is not obviously changed, with high efficiency, green and economic. The whole treatment process is green, economic, high efficiency and solves the common activation method is low efficiency, high energy consumption, environment pollution.
