Abstract

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).

Keywords: artificial photosynthesis; copper indium sulfide; hydrogen evolution; quantum dots; semiconductor.
