1. :
- A method of providing different catalyst surfaces on the opposite surface sides of a substrate comprising;
thermal spraying one surface of the substrate with particulates of one or more than one of a metal hydroxide, metal carbonate, or metal nitrate particles and a noble metal, noble metal hydroxide, noble metal carbonate, or noble metal nitrate to produce a first catalyst composition thereon, and coating a surface of the substrate opposite the one surface by a physical deposition process with one or more than one of ruthenium, rhodium, palladium, silver, iridium, platinum and gold to produce a second catalyst composition thereon.

Abstract
A bi-laterally surfaced substrate in which the first surface consists of one or more than one of cerium oxide, aluminum oxide, tin oxide manganese oxide, copper oxide, cobalt oxide, nickel oxide, praseodymium oxide, terbium oxide, ruthenium, rhodium, palladium, silver, iridium, platinum and gold and the second surface consists of one or more than one of ruthenium, rhodium, palladium, silver, iridium, platinum and gold and micro channel micro component reactors including such substrates in a predetermined formed shape and methods for making the same utilizing a thermal spray on one side and a physical deposition process on the other side.
