NOVELTY - Preparation of tungsten-bismuth/graphene photocatalyst with broad spectrum of performance degradation, involves dissolving 0.97 g bismuth(III) nitrate hydrate in glacial acetic acid aqueous solution, stirring, then adding graphene oxide, ultrasonically dispersing for 1 hour to obtain solution (X), dissolving sodium tungstate in water, stirring to obtain transparent solution (Y), adding solution (X) and solution (Y), stirring for 10 minutes, then heating the mixture, cooling to room temperature, filtering, washing, and drying. USE - Preparation of tungsten-bismuth/graphene photocatalyst with broad spectrum of performance degradation (claimed). ADVANTAGE - The prepared tungsten bismuth/graphene photocatalyst has high efficiency of degradation of rhodamine B dye in wastewater methyl orange under sunlight, and has excellent performance of sulfa-methoxy-pyrimidine in pharmaceutical wastewater and phenol wastewater. The tungsten bismuth/graphene photocatalyst is non-toxic, efficient and inexpensive and has broad spectrum of application. DETAILED DESCRIPTION - Preparation of tungsten-bismuth/graphene photocatalyst with broad spectrum of performance degradation, involves dissolving 0.97 g bismuth(III) nitrate hydrate in 50 mL of glacial acetic acid aqueous solution, stirring, then adding 0.0017-0.034 g graphene oxide, ultrasonically dispersing for 1 hour to obtain solution (X), dissolving 0.33 g sodium tungstate in 20 mL of water, stirring to obtain clear transparent solution (Y), adding solution (X) and solution (Y), stirring for 10 minutes until pH of the glacial acetic acid in the reaction is controlled to less than two, transferring the resulting solution into a sealed Teflon (RTM: polytetrafluoroethylene) autoclave after the pH is stabilized, then heating at 180 degrees C for 3 hours, cooling to room temperature, filtering, washing with water and ethanol three times, then drying at 80 degrees C in a thermostatic oven during overnight. The volume ratio of acetic acid and water in glacial acetic acid aqueous solution is 1:4.
