Fe-Nx-C-based single-atom (SA-Fe-N-C) catalysts have shown favorable oxygen reduction reaction (ORR) activity. However, their application in proton exchange membrane fuel cells is hindered by reduced performance owing to the thick catalyst layer, restricting mass transfer and O2 supply. Metal-organic frameworks (MOFs) are a promising class of crystal materials, but narrow pores exacerbate sluggish mass-transport properties within layer.
