PURPOSE:To obtain an oxidation catalyst for burning a gas such as hydrogen, carbon monoxide and hydrocarbons. CONSTITUTION:The oxidation catalyst is an oxidation catalyst (1) prepd. by making at least one metal or its oxide of group Ib, Va, VIa, VIIa and VIII elements, an oxide of a rear earth element, an oxide of an alkali earth element and zirconium oxide carried on a composite oxide of aluminum and titanium as a carrier, an oxidation catalyst (2) described in (1) prepd. by molding a composite oxide of aluminum and titanium into a honeycomb shape and an oxidation catalyst (3) prepd. by coating a honeycomb-like heat-resistant base material selected from cordierite, mullite or a crystalline composite oxide consisting of MgO, Al2O3 and TiO2 with a catalyst described in (1). |
