<p>A substrate (5) having a catalytic surface (4) having a coating (11) of metal oxide and noble metal particles (1a and 1b) in the nominal diameter size distribution range of less than three microns, preferably less than one micron is produced by thermal spraying a mixture of large size particles (1a and 1b) (greater than 10 microns in nominal size distribution range) of hydroxides, carbonates or nitrates of the metals: cerium, aluminium, tin, manganese, copper, cobalt, nickel, praseodymium or terbium particles; and hydroxides, carbonates or nitrates of the nobles metals: ruthenium, rhodium, palladium, silver, iridium, platinum and gold onto the substrate (5). The coating (11) adheres to the surface (4) and provides desirable catalyst properties.</p> |
