NOVELTY - Preparation of iron sulfide-doped graphene oxide (GO) nitrogen fixation catalyst involves dissolving ferric trichloride hexahydrate, 1,3,5-benzenetricarboxylic acid and graphene in 40 ml water, ultrasonically forming a uniform solution, placing the obtained solution in a reaction kettle at 130-176 degrees C for 72 hours, cooling to room temperature, centrifuging, washing, drying to obtain a precursor, adding the obtained precursor and thiourea into 40 ml deionized water, uniformly stirring, adding in the reaction kettle, heating at 200-176 degrees C for 24 hours, cooling to room temperature, and washing by sulfuric acid and deionized water to obtain iron sulfide-doped graphene oxide composite material. USE - Preparation of iron sulfide-doped graphene oxide catalyst used in electrocatalytic nitrogen fixation reaction for producing ammonia. ADVANTAGE - The method is simple, economical, and provides catalyst having excellent electrocatalytic ammonia production activity.
