Abstract
A method of coating a catalyst layer on a metallic substrate includes preparing a metal oxide and binder slurry to coat onto a metal surface and forming a catalytic layer over the slurry coated surface. The slurry may be made from a binder containing, for example, fully dissolved alumina in the presence of excess nitric acid. The binder may then be mixed with a metal oxide mixture to form the metal oxide-binder slurry. The metal oxide mixture may contain aluminum oxide or partially hydrated aluminum oxide. The metal oxide-binder slurry can be used to coat the surfaces of a variety of metals such as aluminum, titanium, nickel, cobalt, chromium, iron, copper, etc., or their alloys that include brass, as well as stainless steel with or without Al as a component.
