Boosting the electrocatalytic activity of single atom iron catalysts through sulfur-doping engineering for liquid and flexible rechargeable Zn–air batteries

Abstract

A practical strategy is reported to design single-Fe atom decorated S/N-doped C (Fe SAs@S/N–C) catalysts with a high Fe loading of 5.45 wt%. The prepared catalysts exhibit excellent performances for liquid and all-solid-state Zn–air batteries.
