Abstract
A metallic catalyst of three-layer structure of a carrier metal, an interlayer metal having a heat-insulating property by itself, or an interlayer metal capable of forming an oxide having a heat-insulating property or a catalyst surface area-increasing property, deposited on the entire surface of the carrier metal, and a catalyst metal deposited on the interlayer metal is prepared in a shorter production time at a lower cost through simplified process steps by depositing the interlayer metal and the catalyst metal by plating, if necessary, followed by oxidation, or both oxidation and reduction. The metallic catalyst has an improved catalytic activity, especially at a low temperature, in addition to the high mechanical strength.
