Abstract
In this work, we report the preparation of TiO2 and Co-S doped TiO2 nanostructures by sol–gel and wet impregnation method for their potential applications in photocatalytic processes for environmental applications in water purification to degrade pollutant dyes. The crystalline phase, morphology, optical properties, and chemical composition of the synthesized nanoparticles (NPs) are studied by using X-ray diffraction (XRD), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), UV–Visible spectroscopy, and Fourier transform infrared spectroscopy (FTIR). The photocatalytic accomplishment of synthesized nanostructures is observed for the degradation of brilliant green (BG). All the synthesized nanostructures exhibited excellent photodegradation activity. The observed rate of degradation of dye is higher with the Co-S doped TiO2 nanostructures than pure TiO2.
