NOVELTY - Preparing bismuth vanadate-phosphoric acid silver/graphene oxide composite photocatalyst involves growing the needle-shaped silver phosphate on the surface of the bismuth vanadate, to obtain the bismuth vanadate with heterojunction structure, and using graphene oxide to coat the obtained bismuth vanadate with heterojunction structure to obtain the bismuth vanadate-silver phosphate/graphene oxide composite photocatalyst. USE - Method for preparing bismuth vanadate-phosphoric acid silver/graphene oxide composite photocatalyst used in water treatment with organic pollutant (claimed). ADVANTAGE - The method has good stability and excellent photocatalytic activity.
