Abstract

A novel electrocatalytic surface consisting of a Pt monolayer (ML) on an Hf–Ir alloy substrate demonstrated significantly higher activity (six times) and higher selectivity to CO2 formation than bulk Pt in oxidizing ethylene glycol. This enhanced performance could be associated with the high reducibility of Hf oxide and altered electronic property of the Pt ML.
