摘要

•Carbon aerogels of few-layer graphene skeletons by pyrolysis of hydrogel precursors.•Low mass density and high electrical conductivity due to NaCl crystal templates.•ORR activity from the resulting N-doped carbon aerogels.•OER activity from Ni3+ species by Fe(OH)3 oxidation in adsorbed NiFe-LDH colloids.•High-performance bifunctional oxygen catalysts for water splitting and zinc-air batteries.
