Surface-Sensitive Electrooxidation of Carbon Monoxide in Room Temperature Ionic Liquids

Abstract

Electrooxidation of CO at the Pt­(<i>hkl</i>)-electrolyte interface in two different room temperature ionic liquids (RTILs) is probed to be surface-sensitive. Provided data reveal a specific surface structure, (110) sites, which selectively activate CO oxidation in RTILs. This new knowledge is crucial for designing the next generation of Pt nanosized electrocatalysts for the CO oxidation reaction by increasing that type of site on the catalyst surface
