| Abstract: |
Titanium dioxide (TiO₂) nanoparticles have recently been shown to be a possible material in environmental remediation and energy related fields because of their good photocatalytic properties, chemical stability and nontoxic nature. The synthesis high-purity TiO₂ nanoparticles via sol gel method and the research of influence of calcination temperature on their structural morphological and optical properties have been conducted in study. Elemental composition and material purity was verified by energy dispersive X-ray analysis and the optical absorption in UV-Visible spectroscopy. The presence of a bandgap confirms that this material is active in the UV range. We achieved up to 60% of dye degradation under sunlight after 80 minutes using bare TiO₂ nanoparticles, but with very low efficiency when under visible light because of the large bandgap. The findings emphasize that calcination is essential in attaining desirable TiO₂ structure for photocatalytic applications and support its role in solar driven environmental systems.
