Bond breaking/re-formation to tune local coordination: Deliberate construction and subsequent selective cleavage of sacrificial Fe−S bonds render flexible tunability to control the local coordination of metal single atoms. The oxidized sulfur functionalization around the Fe center helps the Fe−N−C reach the ORR volcano-plot apex by optimizing the adsorption strength of the oxygenated intermediates.
