ABSTRACT:
An improved process of preparing a composition, which is effective as a CO oxidation catalyst and contains (a) a SnO.sub.2 -coated porous ceramic material, (b) Pt and/or Pd and (c) at least one compound of Mn and/or Cr, requires the preparation of component (a) by impregnation of a porous ceramic material (preferably a monolith) with a tin carboxylate solution, followed by drying and calcining (so as to decompose tin carboxyte to tin dioxide).
