NOVELTY - The production of bismuth sulfide/titania/graphene complex involves dissolving graphene oxide in absolute ethanol, dispersing, adding bismuth nitrate pentahydrate and sodium hexahydrate to obtain homogeneously dispersed suspension, adding to tetrabutyl titanate, dripping water, stirring to obtain suspension, transferring to PTFE liner containing high pressure hydrothermal reactor for carrying out solvent thermal reaction, cooling, washing resulting product with deionized water and anhydrous ethanol, drying samples obtained by centrifugation and heating in nitrogen atmosphere. USE - Production of bismuth sulfide/titania/graphene complex having high catalytic degradation activity under visible light. ADVANTAGE - The bismuth sulfide/titania/graphene complex enhances the strong absorption capacity of visible light, extends the lifetime of electron-hole pairs, and catalyzes the degradation of organic pollutants. DETAILED DESCRIPTION - The production of bismuth sulfide/titania/graphene complex involves dissolving graphene oxide in 60 ml absolute ethanol, continuously stirring at room temperature, ultrasonically dispersing, adding 0.0227 g bismuth nitrate pentahydrate and 0.0186 g sodium hexahydrate, continuously stirring for 30 minutes to obtain homogeneously dispersed suspension, slowly adding tetrabutyl titanate to suspension, dripping 10 ml water, continuously stirring for 1 hour to obtain uniform suspension, transferring to PTFE liner containing high pressure hydrothermal reactor for carrying out solvent thermal reaction, cooling to room temperature, washing the resulting product with deionized water, washing with anhydrous ethanol for 3 times, drying the samples obtained by centrifugation at 80 degrees C for 8 hours and heating at rate of 4 degrees C/minute in a nitrogen atmosphere.
