ABSTRACT:
There is provided a process for producing a catalyst to convert carbon monoxide in a gas into carbon dioxide. The process comprises causing activated carbon to absorb an aqueous solution of chloroplatinic acid, reducing the absorbed chloroplatinic acid to platinum with a reducing agent, and decomposing an excess of the reducing agent with hydrogen peroxide. The catalyst contains at least 6 mg of platinum per gram of activated carbon.
