Abstract

Surface engineering has been identified as an effective way to maximize the utilization of noble atoms and facilitate the oxygen reduction reaction. However, a cost-effective and highly durable platform for tailoring the electrocatalytic activity, is still absent. Herein, we demonstrate a new and promising catalytic material of antiperovskite-typed PdNFe₃ and construct a high performance PdNFe₃ @Pd catalyst with atomic layers of strained Pd shell. The PdNFe₃ @Pd/C catalyst presents a high mass activity (MA) of 1.14 A mg⁻¹_Pd at 0.9 V, which is 9 and 6 times higher than those of the Pt/C and Pd/C, respectively. More importantly, the excellent performance of PdNFe₃ @Pd/C was also verified in anion-exchange membrane fuel cells and rechargeable Zn−air batteries. Density functional theory calculations reveal that the strain effect aroused by the lattice mismatch between PdNFe₃ core and Pd shell contributes to the enhanced ORR performance by optimizing the binding strength of oxygen intermediates on Pd.
