The invention discloses a nano photocatalytic ceramic material which is prepared from the following raw materials in parts by weight: 6-10 parts of SiO2, 2-8 parts of Al2O3, 1-5 parts of CaO, 1-3 parts of MgO, 3-6 parts of TiO2, 1-3 parts of K2O, 2-4 parts of Na2O, 40-60 parts of diatomite, 15-20 parts of nano shell powder, 6-12 parts of a composite photocatalyst, 2-4 parts of a surfactant, 1-3 parts of a dispersing agent and a proper amount of deionized water. Immobilization of the photocatalyst is directly realized on the ceramic, so that the photocatalytic performance is improved; TiO2 is directly added to the nano ceramic, so that the preparation method is simple; and due to the enrichment and adsorption effects of a porous inorganic ceramic membrane contained in the composite materialand the unique charge transfer performance of carbon nanotubes, the composite material is high in catalytic efficiency, resistant to corrosion and cleaning, high in mechanical strength, stable in structure, free of deformation and long in service life.
