PURPOSE:To remove malodorous gases and harmful gases sufficiently even if the gases to be treated are relatively in low temperature by carrying and having manganese oxide and a composite oxide of silver and manganese as active components in an inorganic oxide support. CONSTITUTION:A deodorization catalyst is carried on a porous support of an inorganic oxide having at least 1m<2>/g specific surface area and contains manganese oxide and a composite oxide of silver and manganese such as AgMn2 O4 AgMnO2, AgMnO4, AgMnO, Ag2MnO, Ag2Mn8O16 as active components. The atomic ratio of Ag and Mn in the active components ranges (1:99)-(80:20)=Ag:Mn. The catalyst further contains Ag and/or silver oxide as an active component. Ceramics of a honeycomb structure, a flat substrate, or a met or a metal structure is coated with those active components. In this way, the catalyst has high removal efficiency of malodorous gases and harmful gases and sufficient deodorization function even if the gas to be treated is relatively in low temperature. |
