▎ 摘  要

NOVELTY - Preparing polyhydric carbon nitride based non-metallic material comprises (i) dissolving graphene oxide in aqueous urea solution, adding reducing agent to perform reduction reaction, obtaining precursor containing urea and reducing graphene oxide, and (ii) uniformly mixing precursor, carbon quantum dots and oxalic acid and calcining at high temperature to obtain polyhydric carbon nitride based non-metallic material. USE - The polyhydric carbon nitride based non-metallic material is useful as photocatalyst in degrading of lincomycin in water (claimed). ADVANTAGE - The material: has functions of wide-area light absorption (absorption edge exceeds 605 nm); promotes generation of active species superoxide radicals; accelerates separation of photogenerated carriers. The method: is simple, and operable. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for polyhydric carbon nitride based non-metallic material, prepared by above method.
