摘要：
The present invention provides a deodorizing method for removing malodorant components by oxidative destruction with ozone in the presence of a catalyst comprising a first component, which is a metal oxide, and a second component which is at least one member selected from the group consisting of titanium dioxide, silver oxide, silica and gold, or a catalyst comprising manganese dioxide and clay.Also, the present invention provides a deodorizing catalyst having its active components carried in a layer, having a thickness of 10 to 200 .mu.m, on the carrier, thereby stably removing malodorant components at a high rate, even when the reaction conditions are changed.
