Control of the selectivity of the oxygen reduction reaction through tuning of molecular steric effects is demonstrated by Ran Long, Rui Cao, and co‐workers in their Communication on page 12742. Selective two‐ or four‐electron oxygen reductions can be achieved by using Co porphyrin atropisomers with similar electronic structures but dissimilar steric effects. This work represents an unparalleled example of improving the oxygen reduction selectivity by tuning only steric effects of the catalysts without changing molecular and electronic structures.
