Shape-Controlled Synthesis and Characterization of CuS Crystal from a Low Temperature Hydrothermal Route
Copper sulfide (CuS) nanocrystals with flower-like and tubular morphology have been successfully synthesized via a facile and convenient hydrothermal route at 75 °C by using CuCl2·2H2O as Cu-precursor, C2H5NS as S-source and CTAB as template molecules. The effect of concentration of reactants and template molecules on morphology has been discussed. X-ray diffraction pattern suggests that the CuS crystals are pure hexagonal phase. The morphology of the products has been studied by scanning electron microscope analysis. The absorption peaks of CuS in UV and near-IR regions indicate that the as-prepared CuS are promising in the development of photoelectric devices.
