Abstract

Cu₂CdSnS₄-CdS nanocomposites are successfully prepared via a two-step solvothermal approach. Powder X-ray diffraction (XRD), Scanning electron microscope (SEM), Photoluminescence (PL) spectroscopy and UV-Vis diffuse reflectance spectroscopy are used to characterized the Cu₂CdSnS₄-CdS nanocomposites. The results show that Cu₂CdSnS₄-CdS nanocomposites present nanoflower structure self-assembling by nanosheets with a thickness of ~50nm and spheroid structure with the average size of 100nm. The band gap is calculated to be 1.5eV. The photodegradation efficiency under visible-light irradiation is reached to 94%, the work provide a new strategy to prepare Cu₂CdSnS₄-CdS nanocomposites for high effective visible-light photocatalytic material.
