Pure TiO2 nanoparticles have been prepared by a novel Photon Induced Method (PIM) without precursor modification. The prepared sample has been calcinated at 500°C, 700°C, and 1000°C to study the effect of calcination temperature on the stability, phase, and morphology of TiO2. XRD analysis reveals an interesting result of an increase in phase stability. This may be accounted for the oxygen richness of the sample which has been confirmed through EDAX. XRD results also reveal a phase transformation from anatase to rutile with increasing calcination temperature. The morphologic analysis performed with HRSEM and HRTEM revel a transformation from nanoparticles to nanorods. The formation of TiO2 is confirmed through the Ti-O vibrational peaks in FTIR and the band gap of the samples have been examined with UV-vis Spectrophotometer. The prepared samples with such high phase stability may be applied for photocatalytic application.
