Ultra-low-temperature growth of CdS quantum dots on g-C 3 N 4 nanosheets and their photocatalytic performance.

CdS quantum dots deposited on carbon nitride (g-C3 N4 ) nanosheets have been synthesized by ultra-low temperature (-60 °C) liquid phase precipitation reactions. The obtained CdS quantum dots were uniformly distributed on the surface of the g-C3 N4 nanosheets with an average diameter of 5 nm. Correspondingly, CdS/g-C3 N4 exhibits a highly enhanced photocatalytic performance.
