Abstract
Abstract The design of cost‐effective and efficient catalysts based on transition metal–based electrocatalysts for the oxygen reduction reaction (ORR) is crucial yet challenging for energy‐conversion devices like metal–air batteries. In this work, we present a cost‐effective strategy for preparing catalysts consisting of single‐atomic Fe sites and Fe 3 C clusters encapsulated in nitrogen‐doped carbon layers (FeSA‐Fe 3 C/NC). The FeSA‐Fe 3 C/NC electrocatalyst demonstrates outstanding ORR performance in alkaline electrolytes, achieving a high half‐wave potential ( E 1/2 = 0.902 V), 4e − ORR selectivity, and robust methanol tolerance. The exceptional ORR catalytic performance is credited to the relatively…
