Abstract
Disclosed herein is a liquid phase oxidation catalyst which comprises a metal substrate and an outectoid coating containing palladium and, molybdenum and/or tungsten coated on the substrate. According to the invention, the oxidation catalyst possessing excellent catalytic activity for oxidation which cannot be obtained by a catalyst prepared by means of pure palladium plating can be obtained. When palladium is compared with platinum, the cost of the latter is about four time larger than that of the former and the gravity of the latter is about two times larger than that of the former so that, if the same thickness of the metal is plated, the cost of the precious metal is advantageously reduced to about 1/8. Also disclosed is a process of preparing this oxidation catalyst.
