Abstract

La-doped γ-Al₂O₃ supported Au catalysts show high activity and selectivity for the PROX reaction under PEMFC operation conditions. The superior performance is attributed to the formation of LaAlO₃, which suppresses H₂ oxidation and strengthens CO adsorption on Au sites, thereby improving competitive oxidation of CO at elevated temperature.
