PROBLEM TO BE SOLVED: To make a catalyst structure not to be restricted in a shape and a size while it is excellent in high temperature corrosion resistance, has high adhesion strength to a base material of the catalyst, and can be manufactured without use of expensive equipment. SOLUTION: The catalyst structure has a ferrite stainless steel made base material composed of at most 0.2 wt.% C, 0.4 to 3.0 wt.% Si, at most 2.0 wt.% Mn, 13.0 to 20.0 wt.% Cr, 0.3 to 3.0 wt.% Mo, and balance consisting of Fe and impurities. In the catalyst, a metal selected from platinum and paradium as an active constituent and rhodium are supported on a support consisting of γ-alumina and cerium stabilized zirconia, and it is supported on a base material. |
