Developing highly efficient and cost‐effective electrocatalysts to boost the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) is vital for the sustainable energy systems. The nitrogen and phosphorus codoped vesica‐like carbons with hierarchical nanoporous structure are synthesized through an efficient self‐polymerization strategy with the template of g‐C 3 N 4 monolith. Featuring sufficient heteroatom‐doping, well‐developed porous hierarchy, and high electrochemical surface area, the fabricated carbon materials exhibit considerable activity and robust stability in both electrocatalyzing ORR and OER, in competition with the precious metal electrocatalysts, which are thus capable of using as air cathode catalysts for rechargeable Zn‐air batteries, affording large discharge current density and impressive operation stability.
