It has been observed in this work and previous studies that Pt,Sn alloy surfaces are very effective catalysts for CO electrooxidation, but not for methanol electrooxidation. Since CO,, is postulated to be an intermediate in methanol electrooxidation on Pt alloy surfaces, the relative inactivity of P
