Cobalt/Nitrogen‐Doped Porous Carbon Nanosheets Derived from Polymerizable Ionic Liquids as Bifunctional Electrocatalyst for Oxygen Evolution and Oxygen Reduction Reaction

Development of efficient catalysts with low cost for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) has been a long‐term pursuit because of their vital role in renewable‐energy technologies including fuel cells and water splitting. Herein, based on polymerizable ionic liquids (PILs) functionalized with nitrate groups as pore former and precursor of C and N, a facile one‐pot thermal treatment method was developed to...
