Abstract

The CuS/ZnO nanocomposite was prepared by using a simple mechanical method. CuS/ZnO nanocomposite synthesized were analysed with XRD and SEM. The average particle size of CuS/ZnO was found to be 30–35 nm. The electrochemical study of nanocomposite was done by using electrochemical impedance and Cyclic voltammetry analysis. CuS nanoparticles mechanically combined with ZnO nanoparticles served as an electron absorber in the nanocomposite, assisting in the enhancement of ZnO photocatalysis. CuS served as an electron collector in the nanocomposite, which aided in the enhancement of ZnO photocatalysis. Experiment performed under visible light source also showed that CuS could aid ZnO in the degradation of Congo red and Phenol. From the UV analysis it was found that CuS/ZnO nanocomposite exhibits better photochemical stability. All of these results suggested that prepared sample could be useful in practical applications.
