▎ 摘 要
NOVELTY - Visible light-driven self-cleaning carbon nitride heterojunction oil-water separation membrane comprises modified layer formed on the surface of basement membrane; the modified layer is obtained by self-assembly of heterojunction nanomaterial and graphene oxide, heterojunction nanomaterial is heterostructure obtained by in-situ growth of iron-based MOFs on the surface of carbon nitride. USE - The oil-water separation membrane is useful in the field of oil-water separation (claimed). ADVANTAGE - The oil-water separation membrane: has excellent oil-water separation performance and visible light-driven self-cleaning performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the visible light-driven self-cleaning carbon nitride heterojunction oil-water separation membrane comprising (1) preparing heterojunction nanomaterials; and (2) constructing oil-water separation membrane.
