Abstract

AbstractHerein, we have reported a new Photon Induced Method (PIM) to the synthesis of enhanced temperature stable anatase phased TiO2 nanoparticles. These TiO2 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 TiO2 has existed a 100% rutile phase at this same temperature. The reversibly improved TiO2 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 TiO2 with high chemical reactivity has a great potential for antibacterial, cancer cells kill, photocatalysis and solar energy conversion applications under solar-light irradiation.Graphic abstract
