PURPOSE:To obtain an oxidation catalyst with high activity and excellent heat resistance and for burning a gas such as H, CO, and HC by making a composite oxide of Al and Ti as a carrier carry at least one of metals of Ib, Va, VIa, VIIa and VIIIa groups of their oxides, an oxide of rare earth elements, and ZrO2. CONSTITUTION:An oxidation catalyst is obtd. by making a composite oxide of Al and Ti as a carrier carry at least one of metals of Ib, Va, VIa, VIIa and VIIIa groups or their oxides, an oxide of rare earth elements, and ZrO2. In another way, an oxidation catalyst can be obtd. by molding the composite oxide of Al and Ti into a honeycomb shape. In addition, an oxidation catalyst is obtd. by coating a honeycomb-like heat resistant base selected among cordierite, mullite or a crystalline composite oxide consisting of MgO, Al2O3 and TiO2 with the above described oxidation catalyst. As the result, an oxidation catalyst with high activity and excellent heat resistance and for burning a gas such as H, CO and HC can be obtd. |
