  • Catalyst for the oxidation of carbon monoxide
    Patent number: 4920088
    Abstract: A composition of matter comprising titania and Pt and/or Pd is prepared by a process comprising one step of heating Pt and/or Pd/impregnated titania with a reducing gas, in particular free hydrogen, at a temperature of about 300.degree.-800.degree. C. Another composition of matter comprising titania and Pt and/or Pd is prepared by a process comprising the steps of coating a porous ceramic material (preferably a monolith) with colloidal TiO.sub.2, drying, impregantion with Pt and/or Pd, drying/calcining, and reducing with a reducing gas, in particular free hydrogen, at a temperature of about 0.degree.-300.degree. C. Both compositions of matter are used as a catalyst in a process for oxidizing CO to CO.sub.2, e.g., in a CO.sub.2 laser.
