The research community has been drawn to titanium dioxide (TiO2) nanoparticles because of their unique functions compared to the bulk material. Due to its high photosensitivity, nontoxicity, high refractive index, strong oxidising ability, high stability, wide band gap, and high photochemical resistance, TiO2 is an effective photocatalyst. In nature, TiO2 is found in crystalline polymorphs such as stable rutile, brookite, and anatase. The major goal of this research was to see how microwave (MW) plasma treatment affected TiO2 nanoparticles made using the sol-gel process. At room temperature, TiO2 nanoparticles were made using the sol-gel technique. 'The' The organic component of the suspension was evaporated by heating it at 300°C for 2 hours. For MW plasma treatment, the nanoparticles were placed in a partially vacuumed chamber. For the oxidation of nanomaterials, plasma treatment is a viable approach. Crystallite size, crystal phases, band gap energy, and surface morphology were measured using X-ray diffraction (XRD), scanning electron microscopy (SEM), and UV-Visible spectroscopy on both plasma-treated and untreated samples. The findings showed the presence of anatase and rutile phases of TiO2 with particle sizes ranging from 0.2 to 14 nm. The particles were trigonal in form and aggregated.
