▎ 摘　　要

NOVELTY - Silver chromate-graphene oxide composite photocatalyst material formed from graphene oxide, whose surface contains solid particles of silver chromate, is new. The average particle diameter of the silver chromate particles is 100-200 nm. USE - Silver chromate-graphene oxide composite photocatalyst material. ADVANTAGE - The silver chromate-graphene oxide composite photocatalyst material can be prepared simply and exhibits high catalytic activity, and stability against visible light (photochemical stability and photocatalytic stability). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of the silver chromate-graphene oxide composite photocatalyst material.
