Abstract:
1. A method for producing a perovskite-type composite oxide, which comprises the steps of: preparing a precursor of the perovskite-type composite oxide by mixing an organometal, salt of a noble metal with another elementary component constituting the perovskite-type composite oxide, and heat-treating the precursor of the perovskite-type composite oxide; wherein the perovskite-type composite oxide is a perovskite-type composite oxide represented by the following general formula (1): wherein A represents at least one element selected from the group consisting of rare-earth elements, alkaline earth metals, and Ag; B represents at least one element selected from the group consisting of Al and transition metals excluding platinum group elements and rare-earth elements; and M represents one or more platinum group elements.
