Abstract
- Drastically lowering the usage of platinum while enhancing activity and stability toward oxygen reduction is critical to promoting energy conversion efficiency in metal‐air batteries. Herein, an efficient oxygen reduction catalyst was rationally designed by constructing ultrasmall Pt and Pt/MoC dual active sites co‐anchored on nitrogen‐doped carbon. Owing to the synergistic effect of the dual active sites, the optimized Pt‐MoC@NC delivers superior oxygen reduction activity with ultralow Pt loading. Especially, the Pt‐MoC@NC shows robust methanol tolerance. As the cathodic catalyst, Pt‐MoC@NC based zinc‐air battery possesses outstanding performance with a large peak power density of 100 mW cm−2 and long charge‐discharge durability.
