The invention provides a visible light catalytic material, a preparation method and application thereof, and belongs to the technical field of catalysts. The visible light catalytic material provided by the present invention includes a carrier and active components supported on the surface of the carrier; the carrier is a conductive ceramic; the active components are P-C 3 N 4 , graphene oxide and bismuth vanadate; the The raw materials for the preparation of conductive ceramics include graphene, alumina and zinc oxide. In the visible light catalytic material provided by the present invention, both P-C 3 N 4 and BiVO 4 can be excited by visible light to generate photo-generated electrons and holes, and the reducing electrons on BiVO 4 will be transferred to P-C 3 N 4 , and will be connected with the P-C 3 N 4 . With oxidative hole recombination, RGO can act as an electron transport medium to enhance the above process. The present invention adopts the active component of specific composition and the carrier to cooperate, and the visible light catalysis material provided has excellent visible light catalysis efficiency and recovery efficiency. |
