摘要

•Phosphate adsorption on Au substrate was investigated by in situ EC-SERS.•Under acidic condition, Au has strong tolerance to phosphate species adsorption.•ORR activities of electrodeposited PtAu alloys were tested in the presence of PA.•PtAu catalysts exhibited better ORR activity than pure Pt in the presence of PA.
