Abstract:
Unlike their bulk counterpart, Cux Iny S quantum dots (QDs) prepared by an aqueous synthetic approach, show promising activity for photocatalytic hydrogen evolution, which is competitive with the state-of-the-art Cd chalcogen QDs. Moreover, the as-prepared Cux Iny S QDs with In-rich composition show much better efficiency than the stoichiometric ones (Cu/In=1:1).
