▎ 摘　　要

NOVELTY - Performing biological synthesizing of ferrous sulfide doped reducing graphene (FeS doped rGO) composite material involves using dissimilar metal-reducing bacteria to decompose organic matter in metabolic process to generate electrons and convert graphene oxide (GO) into reducing graphene (rGO). The water-soluble sulfate and ferric iron is used as final electron acceptor. The FeS nanoparticles are biosynthesized and anchored on rGO sheet to obtain biosynthetic FeS doped rGO composite materials. USE - Method for performing biological synthesizing of ferrous sulfide doped reducing graphene composite material used in fields of environment, catalysis, optics, sensing and electrochemical energy storage performance. ADVANTAGE - The method enables to perform biological synthesizing of ferrous sulfide doped reducing graphene composite material that has wide range of raw material sources, simple operation and high reaction atom economy, and in eco-friendly manner.
