NOVELTY - A mesoporous silica graphene multilayer composite material comprises graphene layer intermediate layer, and mesoporous silica layers upper and lower layers, and the mesoporous layer comprising mesoporous nanosheets formed by close packing of silica. USE - A mesoporous silica graphene multilayer composite material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of mesoporous silica graphene multilayer composite material comprising dissolving 0.25-8.0 mass ratio of templating agent and catalyst into water, obtaining 0.5-20 wt.% surfactant, adding 0.0002-0.00095 mass ratio of graphene sheet, ultrasonicating, obtaining black mixed liquid, dissolving 2.5-30 wt.% silicon source in organic solvent to obtain organic solution, adding black mixed liquid, forming two-phase layered system, reacting at 35-70 degrees C to obtain crude product, and heating at 400-1000 degrees C under inert gas atmosphere.
