Oxygen-assisted stabilization of single-atom Au during photocatalytic hydrogen evolution

Oxygen-assisted stabilization of single-atom Au during photocatalytic hydrogen evolution

Pre-treatment of graphitic carbon nitride (GCN) with H2O2 introduces active C–OH groups that can react with HAuCl4 to immobilize single atom Au(I) in the GCN matrix through creating robust Au(I)–O coordination bonds. This strong bonding can effectively restrict the diffusion of intermediate Au(0) to...
