PURPOSE: To obtain a catalyst for decomposition of ozone not lowering its ozone decomposition performance even in coexistence with NOx or an acidic substance such as lower fatty acid by using one or more of oxides of Mn and Ni as a 1st component and Al oxide as a 2nd component.
CONSTITUTION: This catalyst for decomposition of,.ozone consists of one or more of oxides of Mn and Ni as a 1st component and Al oxide as a 2nd component. These catalytic components may be carried on a known carrier such as alumina, titania, silica or zeolite and this catalyst can maintain its ozone decomposition activity for a long time by carrying the catalytic components especially on titania, silica-titania, silica, zirconia or zeolite as a carrier excellent in acid resistance. The catalytic components are usually carried by 0.1-50wt.%, the shape of this catalyst is not especially limited and various shapes such as honeycomb, pellet, column, plate and pipe shapes may be adopted.
