PROBLEM TO BE SOLVED: To produce fine composite photocatalyst particles excellent in removing malodorous components, contaminants, environmental pollutants, etc., without degrading an org. support, an org. carrier, etc., and to obtain a molding of an org. material. SOLUTION: The objective fine composite photocatalyst particles are surface- coated with porous ceramics. The fine composite photocatalyst particles are produced as follows; fine photocatalyst particles are highly dispersed in a soln. of precursors of the porous ceramics and the precursors are allowed to react on the particles as nuclei to form the porous ceramics on the surfaces of the particles. The fine composite photocatalyst particles are incorporated into at least the surface layer of a molding of an org. material. |
