PdPbM catalysts were synthesized using a solvothermal route by doping various oxophilic elements. Pd14Pb5Co, via Co-induced electronic modulation, achieves exceptional mass activities of 8.02 A mgPd-1 (ethanol oxidation) and 1.02 A mgPd-1 (oxygen reduction). These findings provide a promising strategy for designing high-performance bifunctional fuel cell catalysts.
