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.

Surface modification with a nanomaterial has been confirmed to be an effective strategy to enhance the visible-light photodegradation efficiency of titanium dioxide nanoparticles (TiO2-NPs). In this regard, we used silver as an additive into TiO2-NPs to improve their photodegradation activity under visible light irradiation. Herein, a novel and eco-friendly process was developed to prepare the Ag-doped TiO2 nanohybrid and named as photon-induced method (PIM). The XRD technique showed that the prepared Ag-doped TiO2 has mixed phases of anatase and rutile. However, the rutile-only phase was detected for the pure TiO2-NPs at 700°C of calcination. Ultraviolet-visible (UV-vis) absorption spectra revealed a reduction in the bandgap energy of TiO2 after Ag doping. Besides, the addition of Ag resulted in a significant improvement of TiO2 morphology. Methlyene blue (MB) dye was chosen to be an organic target to investigate the photocatalyst activity of the TiO2-NPs. In this regard, the degradation rate of MB was found to be 100% for the Ag-doped TiO2, which is higher than that of pure rutile TiO2. The incorporation of Ag additive plays a significant role in the improvement of TiO2 stability and photodegradation performance due to the surface plasmon resonance phenomenon.
