Effect of Zn variation in TiO2/ZnS nanocomposite on photocatalysis for the degradation of the hazardous crystal violet dye

TiO2/ZnS nanocomposite was prepared by one-step hydrothermal method. The zinc content in the TiO2/ZnS nanocomposite was varied from M = 0.25, 0.50 and 0.75. The as-prepared TiO2/ZnS nanocomposite was subjected to various morphological characterization such as X-ray diffraction (XRD), UV–Visible spectroscopy, Fourier transform infrared spectroscopy (FTIR), Photoluminescence analysis, Scanning electron microscopy (SEM) and Transmission electron microscopy (TEM). The activity of photocatalysis was investigated by the removal of crystal violet dye in aqueous medium. The crystalline size increased with an increase in zinc quantity. The molar ratio of Zn (M = 0.25) showed maximum photodegradation of 70.07% in TiO2/ZnS nanocomposite.
