  • Catalyst for carbon monoxide oxidation
    Patent number: 4991181
    Abstract: A catalyst for the combination of CO and O.sub.2 to form CO.sub.2 which includes a platinum group metal--e.g., platinum; a reducible metal oxide having multiple valence states--e.g., SnO.sub.2 ; 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, CO.sub.2 lasers operating in a sealed or closed-cycle condition.
    Type: Grant
    Filed: November 30, 1989
    Date of Patent: February 5, 1991
    Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space Administration
