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.
