Au nanoparticles, with an ultra low-loading of Pt and Pd atoms, supported on n-GaN were prepared using electrochemical atomic layer deposition and surface-limited redox replacement. The as-prepared electrocatalysts showed an enhanced performance for formic acid oxidation, and the mass activity reached 3.5 mA μgPtPd−1. The active sites of the PtChem-O species were found to play a key role in formic acid oxidation.
