Title
Effect of deposition sequences on electrocatalytic properties of PtPd/C catalysts for formic acid electrooxidation
Abstract

PtPd/C catalysts with different surface compositions (Pt + Pd, Pt–Pd and Pd–Pt) were synthesized with different deposition sequences, and characterized by electrochemical experiments and XPS measurements. The different catalytic characteristics for formic acid electrooxidation occurred on the three PtPd/C catalysts were preliminarily discussed according to the oxidation pathway. Due to the synergistic effect between Pt and Pd, especially for Pt + Pd, the catalytic stability for formic acid oxidation was greatly increased. The results are helpful in preparing of PtPd catalyst and understanding the oxidation mechanism for formic acid oxidation.
