Pd-induced Pt(Ⅳ) reduction to form Pd@Pt/CNT core@shell catalyst for a more complete oxygen reduction

摘要：

We describe a facile and controllable process for preparing Pd@Pt/CNT core@shell catalysts for the oxygen reduction reaction (ORR) via Pd-induced Pt(Ⅳ) reduction on Pd/CNT.The mass-specific activity for the ORR of the Pd@Pt/CNT catalysts is 7-9 times higher than that of the state-of-the-art Pt/C catalysts, but the yield of H2O2, a harmful species for the stability of catalysts, of the former is only 14.1％ of that of the latter.The reason for the enhanced activity and the lower H2O2 yield on the Pd@Pt/CNT catalysts was studied by DFT calculations.
