Abstract
A catalyst composition which includes palladium and zirconium is formed as a suspension which can be coated onto a metal strip. The composition is formed by combining palladium nitrate with a solution of an alkyl ammonium hydroxide, and mixing the combination with a hydrous zirconium oxide, to form the suspension. The alkyl ammonium hydroxide is preferably tetramethylammonium hydroxide or tetrabutylammonium hydroxide. Nitric acid may be added to the palladium nitrate. The resulting composition shows superior activity and good adhesion to a metal strip. The composition can catalyze a combustion reaction, as well as a steam reforming reaction.
