A catalyst for the combination of CO and O2 to form CO2 which includes a platinum group metal－e.g., platinum; a reducible metal oxide having multiple valence states－e.g., SnO2; and a compound which can bind water to its structure－e.g., silica gel. This catalyst is ideally suited for application to high-powered, pulsed, CO2 lasers operating in a sealed or closed-cycle condition.

A process for the combination of CO and O2 to form CO2 comprising exposing a catalyst consisting essentially of about 1 to 40 percent by weight of a platinum group metal, about 1 to 90 percent by weight of a reducible metal oxide having multiple valence states selected from the group consisting of S

A process for the combination of CO and O2 to form CO2 comprising exposing a catalyst consisting essentially of about 1 to 40 percent by weight of a platinum group metal, about 1 to 90 percent by weight of a reducible metal oxide having multiple valence states selected from the group consisting of Sn, Mn, and Cu, and about 1 to 90 percent by weight of a compound which can bind water to its structure selected from the group consisting of silica gel, calcium chloride, magnesium sulfate, hydrated alumina, and magnesium perchlorate, to a CO and O2 gas mixture.
