NOVELTY - Preparation of mesoporous-shaped graphite type carbon nitride/nitrogen-doped graphene oxide composite material comprises adding nitrogen-doped graphite alkene, hole-shaped carbon nitride and surface active agent to deionized water, heating, stirring, and uniformly mixing to obtain mixed solution; and ultrasonically treating of mixed solution, washing solution, repeatedly washing, and drying to obtain the composite material. USE - Method of preparation of mesoporous-shaped graphite type carbon nitride/nitrogen-doped graphene oxide composite material (claimed). ADVANTAGE - The method has simple process, low cost, high yield and short period, and is environment-friendly and suitable for industrial production.
