Abstract
A composition of matter comprising monolith support material, SnO.sub.2, Pt and/or Pd and at least one Cr compound is prepared by a process comprising the steps of coating a monolith material with colloidal SnO.sub.2, drying, impregnation with compounds of Pt and/or Pd and Cr (and preferably Mn), drying/calcining, and heating in a reducing gas at a temperature of about 0-300.degree. C. This composition of matter is used as a catalyst in a process for oxidizing CO with O.sub.2 to CO.sub.2, preferably in a CO.sub.2 laser.
