Abstract
The significant effect of TiO2 predominantly used as photocatalytic degradation catalyst and could also be used against viruses in future. The modified TiO2 nano-photocatalyst with F and I-doping was prepared using expired egg-white as template through sol-gel method at different concentrations. In this study, aqueous solution of methylene-blue used as target degradation product in presence of prepared TiO2-nanoparticles under simulated-sunlight and LED visible-light. Therefore, particle size of F and I-doped nanoparticles was observed at 12 and 11.8nm (low-concentration) and, 13.2 and 16.2nm (high-concentration) respectively, where removal efficiency exhibited 6.2 and 43.0% at higher and lower-concentration simultaneously of F-doped TiO2 nanoparticles.
