▎ 摘　　要

NOVELTY - Preparing porous carbon-supported graphene-coated nano-nickel particles absorbing material comprises immersing carbon source with the pore structure in the nickel salt solution for 20-30 hours, and then crushing with a mixer, carrying out centrifugal treatment, lyophilizing the centrifuged product, drying the product and heating at 200-250 degrees C to decompose the nickel salt, and then heating at 300-400 degrees C to carbonize the biomass material, and finally heating at 500-800 degrees C to achieve the catalytic carbonization of carbon. USE - The method is useful for preparing porous carbon-supported graphene-coated nano-nickel particles absorbing material (claimed).
