<P>PROBLEM TO BE SOLVED: To provide a composite functional photocatalyst which is capable of conducting the washing, purification, sterilization and deodorization irrespective of the degree of foulings of contaminated materials and further which is capable of accelerating the growth of plants and aquatic animals and to provide an efficient method of a contamination treatment and a growing method of organisms. <P>SOLUTION: The composite functional photocatalyst dispersion is prepared by blending titanium oxide, titanium oxide sol, an oxidation catalyst, ceramic powder and an aqueous binder as a composite functional photocatalyst with water to disperse. The porous composite functional photocatalyst is prepared by having the composite functional photocatalyst supported on an inorganic porous material by impregnating the composite functional photocatalyst with the composite functional photocatalyst dispersion. The washing method of contaminated materials and the growing method of plants are characterized by using a circulation water and a transparent column filled with the porous composite functional photocatalyst, irradiating sunlight and UV light to the porous composite functional photocatalyst while allowing the circulation water to pass through the transparent column and bring the material to be treated into contact with the circulation water. <P>COPYRIGHT: (C)2007,JPO&INPIT |
