Catalyst for carbon monoxide oxidation

摘要

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.
