Enhanced Photocatalytic and Self-Cleaning Performance of Anatase Titanium dioxide Nanoparticles Synthesized via a Modified Sol-Gel Method
Hadeel Salih Mahdi and Mawlood Maajal Ali Abstract: Titanium dioxide nanoparticles (TiO2NPs) had been synthesized using a modified sol-gel technique as well as characterized through UV-Visible spectroscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier transform infrared (FTIR) Spectroscopy, with a band gap of 3.12eV and a pure anatase phase. TiO2NPs had a significant UV absorption as well as an average particle size of approximately 80nm. The objective of this research was to investigate the photocatalytic activity and superhydrophilic behavior of anatase TiO2NPs. According to first-order kinetics, photocatalytic performance has been assessed by evaluating the degradation of organic contaminants under UV irradiation, which resulted in up to 88% removal in 60 minutes. Furthermore, the water contact angle dropped from 70° to less than 5°, demonstrating the TiO₂NPs' strong UV-induced superhydrophilicity and demonstrating their capacity for self-cleaning. These TiO₂NPs appear to be promising options for environmental applications, such as wastewater treatment and self-cleaning coatings in solar panels and building facades, due to their high photocatalytic efficiency as well as superhydrophilic behavior.
Keywords: Titanium Dioxide Nanoparticles, Sol–Gel Synthesis, Photocatalysis, Self-Cleaning.
