Achieving efficient oxygen reduction on ultra-low metal-loaded electrocatalysts by constructing well-dispersed bimetallic sites and interconnected porous channels

Abstract

Hierarchically porous N-doped carbon nanofibers anchored with low-loaded FeCo sites (FeCo@PCNFs) were fabricated via the facile electrospinning method followed by carbonization, showing excellent performance for the ORR and primary zinc–air battery.
