The invention relates to a floating photocatalytic material for water body repair and a preparation method thereof. First, a defective carbon nitride nanosheet is prepared by a secondary calcination method, and then silver carbonate is closely attached to the surface thereof by an in-situ deposition method. Nanoparticles form a composite material, and finally a polystyrene ethyl acetate binder is configured to load the composite material on the surface of perlite to prepare a floating photocatalytic material. The floating photocatalytic material prepared by the invention has the advantages of high pollutant removal efficiency, environmental protection and non-toxicity, simple preparation process, easy solid-liquid separation and reuse, low cost, etc., and can be adsorbed and then degraded in a short time to achieve For the purpose of removing methylene blue and tetracycline in sewage, the invention can be used for sewage treatment in industries such as printing and dyeing, medical treatment, and aquaculture, and provides effective reference for efficient restoration of organic sewage. |
