▎ 摘　　要

NOVELTY - Preparing silver-zinc oxide -graphene aerogel photocatalyst involves adding zinc oxide powder to silver nitrate solution, dropping slowly sodium hydroxide solution dropwise during stirring, washing centrifugally, drying, annealing after finishing, so that nano-silver, that is, silver/zinc oxide, is loaded on zinc oxide, adding silver-zinc oxide to the graphene oxide dispersion, stirring after ultrasonication, adding a cross-linking reducing agent, carrying out a hydrothermal reaction, freezing, and drying for 24-48 hours to obtain a graphene aerogel loaded with silver/zinc oxide powder. USE - Method for preparing silver-zinc oxide-graphene aerogel photocatalyst used in visible light band. ADVANTAGE - The prepared silver-zinc oxide-graphene aerogel photocatalyst provides more active sites for catalytic reactions, while effectively separating electron hole, greatly improves the photocatalytic performance, the adsorption efficiency is high, and has high degradation and reusability. DESCRIPTION OF DRAWING(S) - The drawing shows an electron microscope image of the prepared silver/zinc oxide/graphene aerogel photocatalyst.
