▎ 摘 要
NOVELTY - Photocatalyst composite material comprises core particles and particle shell. The core particles are alumina particles. The particles of the shell comprise aluminum oxide, zinc oxide and graphene, where graphene is coated on the surface of the particles of the shell. The shell particles and core particles are bonded to form polyfunctional compound. The polyfunctional compound comprises silicone group, zinc oxide, thiol group and amine group. USE - Photocatalyst composite material. ADVANTAGE - The photocatalyst composite material effectively utilizes visible light, and has bacteriostatic effect, high conversion efficiency and high catalyzing performance.
