(57) [Abstract] [Purpose] Regarding oxidation catalysts, especially at low temperature and high gas flow rate / The present invention relates to an oxidation catalyst that can oxidize methane with high efficiency under a catalyst volume ratio condition and that has heat resistance even at a high temperature of 1000 ° C. or higher. [Structure] A complex oxide of zirconium and aluminum is used as a carrier, and a group Ib, a group Va, a group VIa, a group VIIa, and a group VIII are used. Oxidation catalyst supporting one or more metals of group elements or oxides thereof and oxides of alkaline earth elements and cordierite, mullite or MgO, Al 2 O 3 , TiO 2 An oxidation catalyst supported on a honeycomb heat-resistant base material made of a crystalline complex oxide of 2 . |
