▎ 摘　　要

NOVELTY - Silver carbonate-graphene oxide composite nanomaterial used as photocatalyst contains bar-shaped silver carbonate and 0.45-3.5 wt.% graphene oxide. USE - Silver carbonate-graphene oxide composite nanomaterial used as photocatalyst (claimed). ADVANTAGE - The method improves dispersion degree of catalyst, accelerates photo-generated charge migration rate, and improves light catalytic activity of composite material. It is environment-friendly and simple. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of silver carbonate-graphene oxide composite nanomaterial comprising ultrasonically dispersing oxidized graphene in deionized water to obtain oxidized graphene dispersion liquid; adding silver nitrate, continuously stirring; reacting; adding sodium bicarbonate; carrying out centrifugal separation, washing with deionized water and absolute ethanol.
