Abstract

The effect of oxidation treatment induced progressive enhancement on oxygen reduction reaction (ORR) activities of PdCo/C catalysts is studied. Based on the XPS characterization, a new term, degree of surface oxidation (DSO), is proposed to illustrate their relationship between ORR activity and surface oxidation extent. It can be obviously found the optimal temperature for the promotion of ORR activity on various oxidized samples is 520 K. The improved ORR activity is ascribed to the formation of surface PdO species with 100% DSO value.
