▎ 摘  要

NOVELTY - A composite photocatalyst comprises graphene covering inkstone-shaped zinc oxide (ZnO) having hexagonal inkstone-shaped sheet structure with inkstone bottom at thickness of 10-40 nm, preferably 20-40 nm, and inkstone wall at thickness of 150-250nm. USE - A composite photocatalyst. ADVANTAGE - The photocatalyst has simple preparation with mild reaction conditions and high yield, thus being convenient for large-scale production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the composite photocatalyst comprising adding zinc acetate and graphene oxide solution to mixed solution of water and N-methylpyrrolidone, reacting for 4-5 hours at 90-98 degrees C to obtain inkstone-shaped ZnO/oxidized graphene, heating to 450-600 degrees C with reducing gases, and annealing for 2-3 hours.
