Abstract

The invention discloses a porous ceramic material with a composite function as well as a preparation method thereof. The porous ceramic material consists of an inorganic porous matrix and a composite-function film which is formed by spray-coating the surface of the inorganic porous matrix with composite-function sol; and the composite-function film is prepared from titanium dioxide, a functional additive and an acidic aqueous solution; the functional additive is selected from two or more complexes with different functions of zinc oxide nanoparticles/clusters, copper oxide nanoparticles/clusters, silver halide nanoparticles/clusters, bismuth vanadate nanoparticles/clusters, graphite-phase carbon nitride nanoparticles/clusters, silver/copper nanocrystals, gallic acid, polyvinyl alcohol and polyethylene phenol. The porous ceramic material with the composite function, which is provided by the invention, belongs to a solid-phase supported catalyst, overcomes the problems that a subparticlecatalyst is difficult to recover and troublesome to reuse and can realize adsorption and decomposition of organic pollutants such as dye and formaldehyde.
