Porous carbonaceous materials simultaneously dispersing N, Fe and Co as bifunctional catalysts for the ORR and OER: electrochemical performance in a prototype of a Zn–air battery

Abstract

Infiltration of the mesoporous structure of SBA-15 silica as a hard template with phenanthroline complexes of Fe+3 and Co+2 allowed the simultaneous dispersion of nitrogen, iron and cobalt species on...

Coordination polymer derived Fe–N–C electrocatalysts with high performance for the oxygen reduction reaction in Zn–air batteries

“…Nowadays, clean and sustainable energy conversion devices, such as fuel cells and metal–air batteries, have been extensively explored to address environmental pollution and fossil fuel energy shortages. 1–4 The cathodic oxygen reduction reaction (ORR), however, possesses an inherent sluggish kinetics that significantly limits the efficiency of energy conversion and thus the output of the devices. 5–7 Currently, noble metal Pt-based (Pt/C, PtNi, etc .)…”
