Air purification film

The utility model relates to an air purification film which comprises an electro-catalytic layer, a conductive layer positioned on the electro-catalytic layer, a photocatalytic layer positioned on theconductive layer and a filter layer positioned on the photocatalytic layer, the electro-catalytic layer, the conductive layer, the photocatalytic layer and the filter layer are prepared from a porousmaterial; air sequentially passes through the filter layer, the photocatalysis layer, the conductive layer and the electro-catalysis layer to be purified and degraded. A photocatalysis technology andan electrocatalysis technology are combined together, so that the capacity of adsorbing and degrading pollutants in air is greatly improved; according to the air purification film, air is in full contact with the air purification film by utilizing the mobility of the air, pollutants in the air are catalytically degraded by utilizing photocatalysis and electrocatalysis, the purification effect isimproved, and the living env
