Description
Chen and co-authors report, in 2026, a nano-island single-atom catalyst that breaks the activity-selectivity trade-off in Fenton-like water treatment. Carbon nitride islands anchored on reduced graphene oxide hold cobalt single atoms in a CoN3C arrangement. The graphene sea beneath lifts the cobalt d-band center and sharpens one orbital near the Fermi level, steering peroxymonosulfate activation toward direct electron transfer rather than indiscriminate radicals.
The system destroyed bisphenol A completely within five minutes, with about 94 percent of the degradation flowing through the selective electron-transfer pathway in their measurements. Its normalized rate constant reached 25 per minute per gram per liter, ahead of the island-free catalyst and most reported rivals, despite lower cobalt loading, 1.25 percent against 1.97 percent for the comparison. Coated onto membranes, the catalyst ran stably for 100 hours in real water matrices with minimal cobalt leaching, a practical step for treatment plants.
