▎ 摘  要

NOVELTY - A graphene and ferrous disulfide composite-loaded anode producing method involves dropping ferric chloride and thiourea solution into oxidized graphene dispersion in a reactor and stirring uniformly, sealing the reactor to perform hydro-thermal reaction to obtain a hydrogel sample. The hydrogel sample is washed with water, freeze-dried and pulverized to obtain graphene and iron disulfide composite nano-powder. The nano-powder is mixed with Nafion solution, isopropyl alcohol and deionized water, and coated on the carbon cloth. The coated carbon cloth is fixed with a fixing piece, and dried. USE - Method for producing graphene and ferrous disulfide composite-loaded anode for microbial fuel cell. ADVANTAGE - The method enables producing the anode with uniform particle morphology, electrochemical performance and better biocompatibility, in a simple manner. DETAILED DESCRIPTION - A graphene and ferrous disulfide composite-loaded anode producing method involves dropping ferric chloride and thiourea solution into oxidized graphene dispersion in a reactor and stirring uniformly, sealing the reactor to perform hydro-thermal reaction at 140-200 degrees C for 12-24 hours to obtain a hydrogel sample. The hydrogel sample is washed with deionized water several times, freeze-dried and pulverized to obtain graphene and iron disulfide composite nano-powder. The nano-powder is mixed with 5% Nafion solution, isopropyl alcohol and deionized water, and coated on the carbon cloth. The coated carbon cloth is fixed with a fixing piece, and dried to obtain a finished product.
