Asymmetrically coordinated single-atom Co-N3S/C catalyst for oxygen reduction reaction

Abstract

Tailoring the coordinative structure of a single-atom catalyst is a universal yet challenging route toward enhanced electrocatalysis. Herein, a coordinative compound impregnation strategy is reported for the synthesis of a Co-N₃S/C catalyst with asymmetric coordination for the oxygen reduction reaction, which demonstrates excellent performance in a Zn–air battery.
