Abstract
This application discloses catalysts and methods of making the catalysts. In one embodiment, a catalyst comprising: a reduced precious group metal in an amount greater than about 30 wt % based on the total precious group metal weight in the catalyst, wherein the catalyst oxidizes volatile organic compounds and/or carbon monoxide at a temperature of about 150° C. or lower, is disclosed. In another embodiment, a catalyst for oxidation of formaldehyde, methanol, formic acid, and/or carbon monoxide to form carbon dioxide at a temperature of from about 20° C. to about 45° C. and at about atmospheric pressure, the catalyst comprising: a reduced precious group metal dispersed on a support selected from the group consisting of CeO2, TiO2, ZrO2, Al2O3, SiO2, and combinations thereof, is disclosed.
