Developing bifunctional catalysts for oxygen electrochemical reactions is essential for high‐performance electrochemical energy devices. Here, a Mott–Schottky heterojunction composed of porous cobalt–nitrogen–carbon (Co‐N‐C) polyhedra containing abundant metal‐phosphides for reversible oxygen electr...
