ABSTRACT:
A method of making a catalyst for cleaning exhaust gas from an engine including steps of preparing corrugated metallic panels and plane metallic panels, laminating the plane metallic panels with the corrugated metallic panels alternatively side by side to form a honeycomb structure of a metallic carrier, forming at least two layers of a base coat portion and an over coat portion of alumina based coating on the metallic carrier sequentially, and impregnating catalytic components into at least the outermost layer of the alumina based coating.
