NOVELTY - The utility model claims a photo-catalyst sponge-shaped porous film, comprising a silicon-based resin layer; the inner part of the silicon-based resin layer is filled with titanium pigment; the inner part of the silicon-based resin layer is equidistantly arranged with a first pipe body; the upper surface and the lower surface of the silicon-based resin layer are symmetrically fixedly connected with with two graphene layers; one side of the graphene layer far away from the silicon-based resin layer is adhered with a radiating layer; The utility model uses silica-based resin layer with titanium pigment as substrate, so that the utility model has strong tensile force; when the water body passes through, it is not easy to make the utility model fall off; relative to the traditional photocatalyst coating, the utility model has double-layer photocatalyst layer, which increases the photocatalyst area, improves the use effect; The utility model is simple to maintain, convenient to change, through the arrangement of a plurality of first tube body and the second tube body, enhances the drainage performance of the utility model, is more convenient for large flow of water body.
