<p>A carrier (A) of thermoplastic polymer is mixed and contacted with photocatalytic particles (B) preferably in a rotary heating drum to fusion-bond the particles (B) to surface portions of the carrier (A) in such a manner that multiple particles (B) are stacked in directions perpendicular to the surfaces of the carrier (A), whereby a photocatalyst-bearing material can be produced, which is capable of exhibiting a high photocatalysis for a long period of time. When water is the object of treatment, the specific gravity of the photocatalyst-bearing material is preferably 0.7 to 1.3, especially preferably 0.9 to 1.1.</p> |
