PURPOSE: To decontaminate gases easily, accurately and efficiently by depositing catalytic components capable of photodecomposing and/or heat decomposing contaminated gases on a carrier capable of being heated to thereby prepare a catalyst for decomposing the contaminated gases.
CONSTITUTION: The catalitic components capable of photodecomposing and/or heat decomposing contaminated gases are deposited on a carrier cable of being heated by a heat source such as SiC, BaTiO3, stabilized zirconia, various perovskite oxides and Ni-Cr to thereby prepare a catalyst for decomposing the contaminated gas. By way of example, active carbon is available as the catalystic component capable of adsorbing the contaminated gas and titanium oxide as the catalitic component capable of photodecomposing the same. The catalyst so formed is irradiated with light and heated upon regeneration, whereby the adsorbed contaminants can be decomposed and removed.
