N, P co‐doped hierarchical porous graphene as a metal‐free bifunctional air cathode for Zn − air batteries

The development of high‐efficiency Zn−air batteries represents one of the emerging energy storage and conversion technologies. In this work, hierarchically structured N, P co‐doped graphene (NPHG) has been synthesized through the chemical polymerization of aniline and phytic acid in the presence of...
