Carbon-supported PdCFe/C catalyst was synthesized by impregnation method. X-ray absorption spectroscopy (XAS) revealed the incorporation of C atoms in PdFe/C clusters and high-temperature annealing was facilitated the formation of the Pd−Fe−C alloy. The catalytic activity oxygen operated via reduction reaction (ORR) of Pd−Fe−C alloy demonstrated the strong dependence upon composition of Pd−Fe−C catalysis, the half-wave potential raise with the increase of iron content. A cyclic voltammetry (CV… CONTINUE READING
