Electronic interplay: synergism of binary transition metals and role of M–N–S site towards oxygen electrocatalysis†
Abstract
Towards rational catalyst development, a binary Fe–Co centre has been coordinated with S and N in a nanocarbon matrix. An electronic drift between Fe–Co and an extended +R effect from the S dopants towards the metals through the pz orbital of N are beneficial for oxygen electrocatalysis and a zinc–air battery.
