    摘要： There is disclosed a catalyst structure for ozone decomposition which comprises a thin porous carrier material which has many micropores in the direction of the thickness of the carrier material and has an ozone decomposition catalyst supported thereon.Also disclosed is a method of ozone decomposition using such a catalyst structure, in which preferably the catalyst structure comprises a thin porous carrier material which has many micropores not less than 30 .mu.m in diameter in the direction of the thickness of the carrier material and has an ozone decomposition catalyst supported thereon. The carrier material may be of an electrically resistant material, and may be electrified and heated while a gas containing ozone is forcibly passed therethrough.

    摘要： A catalyst for decomposing ozone comprising a carrier and a catalytic active substance having ozone resolvability carried thereon in a thickness of 10 to 200 .mu.m. Consequently, ozone can efficiently be removed. The invention also includes the catalytic active substance or ozone adsorption substance which is contained in the carrier, such that the combination of the carrier and its contained material has ozone resolvability or ozone adsorbing ability in itself. Accordingly, the combination of these two features allows the thickness of the catalytic active substance carried on a carrier surface to be reduced to the range from 5 to 100 .mu.m. Thus, improved productivity, durability of the catalyst and ozone removing efficiency are provided.
