Facile synthesis of improved anatase TiO2 nanoparticles for enhanced solar-light driven photocatalyst

Herein, we have reported a new Photon Induced Method (PIM) to the synthesis of enhanced temperature stable anatase phased TiO 2 nanoparticles. These TiO 2 nanoparticles exhibited an anatase phase even after calcinating at 800 °C for average crystallite size is 9 nm with a bandgap is 2.98 eV, stretch...

Summary:Herein, we have reported a new Photon Induced Method (PIM) to the synthesis of enhanced temperature stable anatase phased TiO 2 nanoparticles. These TiO 2 nanoparticles exhibited an anatase phase even after calcinating at 800 °C for average crystallite size is 9 nm with a bandgap is 2.98 eV, stretching into the visible light region are identified from DRS, and photoluminescence spectroscopic studies. Whereas, the standard and others reported TiO 2 has existed a 100% rutile phase at this same temperature. The reversibly improved TiO 2 has attained from the PIM method by tuning of oxygen vacancy during the preparation condition. The enhanced methylene blue dye under in the solar-light 100% degradation within 10 min is a very novel report, not reported elsewhere. The obtained pure anatase TiO 2 with high chemical reactivity has a great potential for antibacterial, cancer cells kill, photocatalysis and solar energy conversion applications under solar-light irradiation.
