Abstract

Abstract Anion-exchange membrane fuel cells and Zn–air batteries based on non-Pt group metal catalysts typically suffer from sluggish cathodic oxygen reduction. Designing advanced catalyst architectures to improve the catalyst’s oxygen reduction activity and boosting the accessible site density by increasing metal loading and site utilization are potential ways to achieve high device performances. Herein, we report an interfacial assembly strategy to achieve binary single-atomic Fe/Co-N x with high mass loadings through constructing a nanocage structure and concentrating high-density accessible binary single-atomic Fe/Co–N x sites in a porous shell. The prepared FeCo-NCH features metal loading with a…
