As a result, such a catalyst is obtained that iron-group elements of metal states are deposited on a compound oxide having a tetragonal zirconia structure in which rare earth elements and a part of iron-group elements are taken and stabilized. Sometimes a part of iron-group elements contained in the compound oxide having the tetragonal zirconia structure is lost by a reaction with carbon monoxide. Even in that case, the stability of a structure of a carrier is not damaged. COPYRIGHT: (C)2009,JPO&INPIT
