NOVELTY - Nanometre porous graphene material comprises nickel salt, polypropylene powder, citric acid and carbon source. The nickel salt, polypropylene powder and citric acid are added to a reaction kettle for hydrothermal reaction. Filtering, washing, drying and calcining process is performed on the reaction product in sequence to obtain a first reactant. The first reactant is placed in a reactor to continuously raise the temperature. A protective gas and hydrogen is feed into the reactor to obtain a second reactant after reaching the first reaction temperature while feeding protective gas. The second reactant is placed in the reactor to continuously raise the temperature while feeding the protective gas. A protective gas and a carbon source are introduced into the reactor so as to deposit and form graphene on the second reactant to obtain a nanoporous graphene material, where carbon source comprises methane or ethylene. USE - Used as nanometre porous graphene material. ADVANTAGE - The nano porous graphene material has controllable product porosity, high mechanical strength and low specific surface area.
