Unlike their bulk counterpart, Cu x In y 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 Cu x In y S QDs with In‐rich composition show much better efficiency than the stoichiometric ones (Cu/In=1:1).
