▎ 摘 要
NOVELTY - Nitrogen doped bismuth vanadate with oxygen vacancy graphene oxide nanocomposite photocatalytic material comprises nitrogen doped bismuth vanadate with oxygen vacancy and nitrogen doped graphene oxide to form the nano-composite structure. USE - The material is useful in photocatalytic degradation of pollutants (claimed). ADVANTAGE - The material: has narrow band width, has wide range of light response, high electron hole separation rate and strong catalytic capability; and significantly improves solar energy utilization efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing nanocomposite photocatalytic material comprising dispersing bismuth(III) nitrate, sodium metavanadate, sodium azide and graphene oxide through solvothermal reaction.
