•A series of PdPt@Au nanoparticles with uniform size and structure are fabricated.•A correlation between CO electrocatalytic oxidation and ATR-IR peak is discovered.•The core@shell samples could be more active than alloy samples in CO electroxidation.
A series of PdPt@Au core@shell nanopaticles (NPs) of similar size are synthesized with composition controlled cores and thickness controlled shells. Their CO electrocatalytic oxidation properties change with the composition of the cores, showing a volcano curve. A correlation between the properties of CO electrocatalytic oxidation and the location of adsorbed CO ATR-IR peak is discovered. Attenuated Total Reflection-Infrared Spectroscopy (ATR-IR) shows that samples which have the strongest monodentate CO are most active in CO electrocatalytic oxidation.
