NH3 plasma-etching-derived porous N-doped carbon nanotubes with FeP nanoparticles and intrinsic carbon defects for boosting oxygen reduction in rechargeable Zn–air batteries

Abstract

The formation of intrinsic carbon defects and phase engineered FeP nanoparticles regulated by NH3 plasma etching significantly enhanced the oxygen reduction reaction performance of N-doped carbon nanotubes.
