PURPOSE:To rapidly and efficiently remove harmuful substances through using the photocatalyst bodies in an uniformly fluidized state to a fluid contg. the harmful substances to be treated by employing as the photocatalysf bodies polymer particles each of which contains photocatalyst particles on its surface and/or in the vicinity of its surface. CONSTITUTION:The photocatalyst bodies are produced by polymerizing a monomer in the presence of particles of a photocatalyst such as titanium oxide, etc., to form fluorine polymer and/or si1icon polymer particles, etc., each of which contains photocatalyst particles on its surface and/or in the vicinity of its surface. At this time, the photocatalyst particle content of each of the polymer particles is 0.1 to 80wt.% based on the weight of the polymer particle. The photocatalyst bodies are irradiated with light of a wavelength having higher energy than the band gap of the photocatalyst in the presence of the harmful substances to be treated. Accordingly, the photocatalyst bodies having small specific gravity can be uniformly fluidized with the fluid contg. the substances to be treated to remove organic halogen compounds, malodorous gases, etc. |
