Novel materials for self-cleaning glass surfaces are being researched due to rising demand for environmentally friendly and self-cleaning glass surfaces. Titanium dioxide (TiO₂) nanoparticles have significant photocatalytic ability, making them a good fit for self-cleaning coatings on glass surfaces. The sol-gel synthesis is carried outsince the method allows for precise control of particle size and shape to formulate TiO₂ nanoparticles. The hydrolysis and condensation of titanium alkoxide precursors are followed by controlled heat treatment to yield TiO₂ nanoparticles. UV-Vis, FTIR-ATR, Particle size analysis, and SEM techniques were used to analyse the structural, morphological, and optical properties of the synthesised TiO₂ nanoparticles. The contact angle technique is used to assess the self-cleaning characteristics of nanoparticles and the results are compared with silica dioixide nanoparticles synthesised via the same sol gel route. By providing a sustainable method for preserving transparent surfaces, the present research has the potential to benefit a wide range of disciplines, including architecture, automobiles, and renewable energy.
