Fluorine and phosphorus atoms cooperated on an N-doped 3D porous carbon network for enhanced ORR performance toward the zinc–air batteries

Abstract

A three-dimensional N-doped porous carbon nanosheet catalyst cooperated by fluorine and phosphorus atoms was prepared in this work, which showed high oxygen reduction performance in 0.1 M KOH and a power density of 138 mW cm−2 in zinc–air battery.
