Striking gold: A pathway to stable, high-activity catalysts from gold nanoclusters: Researchers design a stable, high-performance photocatalyst from gold nanoclusters by removing the protective molecules around them

Precise metal nanoclusters (NCs) are ideal for developing practical catalysts for chemical reactions. However, their catalytic activity is reduced either due to protective molecules called 'ligands' surrounding them or aggregation resulting from ligand removal. In a new study, scientists elucidate the ligand removal mechanism for gold NCs and irradiate them with UV light to prevent aggregation, creating a high-functioning photocatalyst.
