Abstract
CO adsorption on nanometer-thin layer of surface alloys of Pt-Ru and Pt-Pd prepared by electrochemical codeposition has been studied using in situ FTI R spectroscopy. Abnormal infrared effects (AIREs) that consist of the enhan cement of IR absorption by adsorbed CO on different surface sites and the i nversion of IR band direction have been observed on the thin-layer prepared . The results also demonstrate the considerable significance of Pt-Ru and P t-Pd surface alloys in electrocatalysis applications.
