Nature’s oxygen-evolving complex of photosystem II is a multinuclear manganese cluster. Whether mononuclear manganese can also efficiently catalyse water oxidation has been a long-standing question. Now, Li and co-workers show that single atoms of manganese can be anchored on nitrogen-doped graphene to catalyse the oxygen evolution reaction. Credit: Water image Frankie Angel / Alamy Stock Photo.
