▎ 摘　　要

NOVELTY - Preparation of Z-type graphene-sulfide composite photoanode material involves pretreating conductive glass, performing electrochemical deposition on the pretreated conductive glass surface to obtain graphene-manganese sulfide layer, and depositing a tin sulfide layer on the surface of the graphene-manganese sulfide layer. USE - Preparation of Z-type graphene-sulfide composite photoanode material used in anticorrosion of marine engineering concrete structural metal material (all claimed). ADVANTAGE - The Z-type graphene-sulfide composite light material positive electrode can effectively solve or improve the problem that the protection effect of the light positive electrode protective material the existing technology to the metal material of the marine engineering concrete not ideal, realizing efficient photoelectric negative electrode of ocean engineering structure, improving the durability of the ocean engineering structures.
