▎ 摘　　要

NOVELTY - Preparation of graphene surface load zinc oxide nanoparticle composite material comprises dispersing graphene prepared by chemical oxidation-reduction method in an alcohol solution, adding 1-pyrenic acid, and stirring; adding zinc acetate and stirring; adding soluble alkali into the alcohol solution and stir; and adding second solution into the first solution, stirring for more than 7 days at 0-15 degrees C, and separating solid and liquid. USE - The method is used for preparing graphene surface load zinc oxide nanoparticle composite material in photocatalytic, super capacitor, and sensor (claimed). ADVANTAGE - The method uses combined with low-temperature long-period reaction mode, achieves high-density and uniform distribution of zinc oxide nanoparticles on the surface of graphene, and improves the performance of the graphene surface loaded zinc oxide nanoparticle composite material in photocatalysis, super capacitor and sensor capabilities.
