Hydrophobic Polymer-Coated Metal Oxide Catalysts for Effective Low-Temperature Oxidation of CO under Moisture-Rich Conditions

摘要

For the past several decades, the oxidation of carbon monoxide (CO) has become important in numerous applications, such as air/gas purification, life-support respirators, exhaust pollution reduction for automobiles/factories and Pt electrode protection in the low-temperature fuel cell system. This results in a pressing need for CO oxidation catalysis; and many catalyst systems (noble metals, metal oxides, and composites) have been studied for high CO conversion at various temperatures and environments. Among them, metal oxide catalysts with low production costs and high CO oxidation activity proved to be the most attractive.
