PURPOSE:To provide a highly active catalyst capable of oxidizing and decomposing a malodorous substance such as acetaldehyde at ordinary temp. or a relatively low temp. by oxygen in air without using ozone. CONSTITUTION:Silver and/or a silver compd. is supported on an adsorbable porous carrier having large pores and a large specific surface area like 13X zeolite or gamma-alumina to obtain a malodorous substance removing catalyst. By using this catalyst, a harmful substance such as acetaldehyde is decomposed and removed at a relatively low temp. by oxygen in air without using a harmful substance such as ozone as an oxidizing agent. |
