The material was analyzed for its structural property from XRD analysis and optimized to yield single phase of CuS semiconductor. Optical property of as-synthesized CuS semiconductor was studied using UV-Vis spectroscopy and band gap was calculated. The photocatalytic activity of the CuS was studied using crystal violet as model pollutant.
