NOVELTY - Producing graphene composite antimony sulfide photo-catalyst involves adding graphene oxide to the glycol and subjecting to ultrasonic peeling for 1-3 hours to obtain 0.5-2mg/mL graphene oxide glycol dispersion. The stannous chloride is added in the 0.02-0.03mg/mL graphene oxide glycol dispersion. The obtained product is stirred and dissolved. The tartaric acid is added to the obtained product, where quantity of tartaric acid is 2-4 times of stannous chloride. The obtained product is stirred continuously to dissolve tartaric acid to obtain mixed solution. USE - Method for producing graphene composite antimony sulfide photo-catalyst used for preparing graphite based composite material (claimed). ADVANTAGE - The method enables to produce graphene composite antimony sulfide photo-catalyst in simple, and cost-effective manner and high good catalytic activity. DETAILED DESCRIPTION - Producing graphene composite antimony sulfide photo-catalyst involves adding graphene oxide to the glycol and subjecting to ultrasonic peeling for 1-3 hours to obtain 0.5-2mg/mL graphene oxide glycol dispersion. The stannous chloride is added in the 0.02-0.03mg/mL graphene oxide glycol dispersion. The obtained product is stirred and dissolved. The tartaric acid is added to the obtained product, where quantity of tartaric acid is 2-4 times of stannous chloride. The obtained product is stirred continuously to dissolve tartaric acid to obtain mixed solution. The sulfur is added to the mixed liquid, where quantity of sulfur source is 2-3 times of stannous chloride. The obtained solution is subjected for magnetic stirring for 20-60 minutes. The obtained solution is stirred and refluxed at 120-180 degrees C for 12-18 hours. The obtained solution is cooled to the room temperature. The obtained product is centrifuged and separated to obtain black precipitate. The obtained product is washed ultrasonically with de-ionized water and absolute ethyl alcohol and dried to obtain graphene composite antimony sulfide photo-catalyst.
