Provided is a non-noble metal-based exhaust gas purifying catalyst which is capable of removing an unreacted material such as carbon monoxide in an exhaust gas at low temperatures. An exhaust gas purifying catalyst of the present invention contains a ceria-based carrier and a complex oxide of cobalt and an additional metal element, said complex oxide being supported by the ceria carrier. The additional metal element contains a metal element that is selected from the group consisting of copper, silver, magnesium, nickel, zinc and combinations of these elements.

Exhaust gas purifying catalyst and method for producing same

An exhaust gas purification catalyst including a catalyst support and bimetallic particles supported thereon, wherein said bimetallic particles include an at least partial solid solution of rhodium and iridium and have a diffraction peak at 40.66&#xb0;&#x3c;2&#x3b8;&#x3c;41.07&#xb0; in X-ray diffraction with a CuK&#x3b1; ray. A method for producing an exhaust gas purification catalyst, includes heating a mixed solution containing a rhodium salt, an iridium salt and a reducing agent at a temperature sufficient to reduce rhodium and iridium, thereby producing bimetallic particles including an at least partial solid solution of rhodium and iridium; and supporting the produced bimetallic particles on a catalyst support.
