NOVELTY - Method for preparing graphite oxide-loaded bismuth tungstate-based photocatalyst involves (a) ultrasonically dispersing sodium oleate, bismuth(III) nitrate pentahydrate and sodium tungstate dehydrate in ethylene glycol solution to obtain mixed solution (A), (b) adding graphene oxide to mixed solution (A) and stirring and mixing evenly, (c) reacting mixed solution obtained in step (b) in a hydrothermal reactor and (d) ultrasonically washing the reactant obtained in step (c), drying and crushing dried mixture. USE - The method is useful for preparing graphite oxide-loaded bismuth tungstate-based photocatalyst (claimed). ADVANTAGE - The prepared graphite oxide-loaded bismuth tungstate-based photocatalyst degrades organic pollutants rate of 99% or more and exhibits rhodamine B (RhB) removal rate of 90% or more. DETAILED DESCRIPTION - Method for preparing graphite oxide-loaded bismuth tungstate-based photocatalyst involves (a) ultrasonically dispersing sodium oleate, bismuth(III) nitrate pentahydrate and sodium tungstate dehydrate in ethylene glycol solution to obtain mixed solution (A), (b) adding 3-5% graphene oxide to mixed solution (A) and stirring and mixing evenly, (c) reacting the mixed solution obtained in step (b) in a hydrothermal reactor at 200-220 degrees C for 22-24 hours and (d) ultrasonically washing the reactant obtained in step (c), drying and crushing to obtain bismuth tungstate/bismuth oxide photocatalyst supported with graphene oxide.
