NOVELTY - Tetrahydrate ferrous chloride is dissolved in deionized water, and stirred to obtain solution having concentration of 0.04-0.08 mol/L. 3% Polyvinyl pyrrolidone and polyvinyl acetate solution is added to resultant mixture, and sodium hydroxide solution is dripped. Sulfur is added to resultant solution, and graphene oxide is dispersed. The obtained solution is added to a stainless steel reactor, and hydrothermal reaction is carried out at 180-200 degrees C. The obtained mixture is cooled, maintained and centrifuged to obtain graphene oxide/iron sulfide composite nanoparticles. USE - Manufacture of graphene oxide/iron sulfide composite nanoparticles (claimed). DETAILED DESCRIPTION - Tetrahydrate ferrous chloride is dissolved in deionized water, and stirred to obtain solution having concentration of 0.04-0.08 mol/L. 3% Polyvinyl pyrrolidone and polyvinyl acetate solution is added to the resultant mixture, such that volume ratio of polyvinyl acetate solution and deionized water is 1:4-3:4, and volume ratio of ferrous chloride tetrahydrate and polyvinyl pyrrolidone is 1:2-2:1. To the obtained stirred solution sodium hydroxide solution is dripped, such that molar ratio of sodium hydroxide and ferrous chloride tetrahydrate is 4:1-2:1. Sulfur is added to the resultant solution, such that the molar ratio of sulfur with respect to ferrous chloride tetrahydrate is 4:1-7:1. Graphene oxide is dispersed to the obtained solution, such that the mass ratio of graphene oxide with respect to ferrous chloride tetrahydrate is 6:1-4:1. The obtained solution is added to a stainless steel reactor, and hydrothermal reaction is carried out at 180-200 degrees C for 12-24 hours. The obtained mixture is cooled, maintained and centrifuged to obtain graphene oxide/iron sulfide composite nanoparticles.
