<i>P</i> ‐Block Atomically Dispersed Antimony Catalyst for Highly Efficient Oxygen Reduction Reaction

A p-block atomically dispersed antimony with Sb−N4 configuration has been developed and used as highly efficient oxygen reduction reaction (ORR) electrocatalyst. The excellent ORR activity is credited to the p orbital interaction between Sb cation and O2, which facilitates the charge transfer and generates appropriate adsorption strength for oxygen intermediates, lowering the energy barrier and modulating the rate-determining step.
