摘要：
A catalyst for decomposing ammonia by oxidation is produced by converting the surface layer of steel material of specified shape resembling a ring, honeycomb, plate or the like to an aluminum alloy, treating the steel material with an aluminum dissolving solution to dissolve out the aluminum and to render the surface layer porous, subjecting the steel material to oxidation treatment to obtain a catalyst carrier, and causing the carrier to support platinum.
