▎ 摘　　要

NOVELTY - Controllable preparation of carbon-coated bismuth vanadate particle/graphene composite photocatalyst is performed by dissolving bismuth nitrate and ammonium metavanadate precursor powder in mixed reagent of glycerol, alcohol, and water to obtain bismuth vanadate precursor solution, ultrasonically dispersing with graphite oxide, performing centrifugal filtration, drying in oven, and performing heat treatment at 400-600 degrees C for 5 hours under nitrogen atmosphere. USE - Controllable preparation of carbon-coated bismuth vanadate particle/graphene composite photocatalyst for photocatalytic decomposition of organic pollutant and water oxygen generator. ADVANTAGE - Product has excellent catalytic performance and good conductivity. DESCRIPTION OF DRAWING(S) - The drawings show transmission electron microscope images of carbon-coated bismuth vanadate particle/graphene composite photocatalyst at different resolutions.
