The γ-Al2O3 and AgCl/Al2O3 catalyst powders were coated on a stainless steel substrate and influences of preparation methods on coating and NOX reduction were studied. The stainless steel SUS304 was coated by Electrophoretic Deposition Method using dehydrated aluminum nitrate as a binder. The AgCl/Al2O3 catalyst was produced by three kinds of methods, and the difference in the NOX reduction catalyses of coated samples was examined. XRD and SEM were used to study the crystalline structure and cross-section of the coatings. The coatings of γ-Al2O3with the thickness of 3-5 μm and AgCl/Al2O3 catalyst with the thickness of 3-8 μm were made on the surface of SUS304 plate without exfoliation. The NOX conversion of the coated sample with catalyst was about 70 % at the maximum. Furthermore, there was a peak in NOX reduction at the different temperature in the case of the catalyst produced under the conditions A.
