Methane reforming catalyst and method for producing the same

Abstract

A method for producing a methane reforming catalyst according to one embodiment of this application includes the steps of: oxidizing the surface of a porous metal support; forming a first coating layer containing a first inorganic oxide on the porous metal support whose surface has been oxidized using ALD (atomic layer deposition), and then performing a first heat treatment step to produce a catalyst precursor provided with the first coating layer; and coating the catalyst precursor provided with the first coating layer with a solution containing a precursor of a perovskite compound represented by the chemical formula 1, and then performing a second heat treatment step to produce a catalyst provided with a second coating layer.
