Introduction

CO electrooxidation is a reaction of great technological importance, which has been widely used as a prototype electrochemical reaction in fundamental electrocatalysis. In proton exchange membrane fuel cells (PEMFC) fed by hydrogen, presence of CO in the feed leads to significant voltage losses due to the strong CO adsorption and concomitant active site poisoning of Pt-based anode catalysts. In low-temperature fuel cells which utilize C1- and C2-oxygenated molecules like methanol, ethanol, formaldehyde, and formic acid as fuels, CO is formed as an intermediate which is blocking active sites and greatly impeding the anode reaction. For these applications, the use of CO-tolerant catalysts is of utmost importance. Investigation of CO electrooxidation on model single crystal and nanostructured electrodes has strongly added to the advancement of the fundamental electrocatalysis in particular in what concerns the understanding of the kinetics of electrocatalytic reactions,...
