“…8a and b. The peaks at 458.3 eV and 463.8 eV are ascribed to the Ti2p3/2 and Ti2p1/2 of TiO 2 [42]. The peaks at 529.5 eV and 531.0 eV are attributed to the bulk O 2 from TiO 2 and -OH adsorbed on the surface of MT 22 , respectively [42].…”

“…From the high resolution core-level spectra of titanium, two peaks at 464.6 eV and 463.8 eV ( Fig. 8(a)) can be seen, which are ascribed to the Ti2p3/2 and Ti2p1/2 of TiO 2 [29]. However, there is also a small peak at 461.3 eV, and we tentatively ascribe this peak to the Ti 3+ , which might be related with oxygen vacancy, and contributes much to the visible light activity of TiO 2 [30].…”

Catalyst recovery is one of the most important aspects that restrict the application of TiO2 photocatalyst. In order to reduce restrictions and improve the photocatalytic efficiency, a hierarchical porous TiO2 monolith (PTM) with well-defined macroporous and homogeneous mesoporous structure was prepared by using a sol-gel phase separation method. P123 was used as the mesoporous template and graphene oxide was applied to increase the activity and integrity of the monolithic TiO2. According to scanning electron microscopy and the Barrett-Joyner-Halenda measurements, PTM3 is mainly composed of 10 nm anatase crystallines with 3.6 nm mesopores and 2-8 μm macropores. Further characterization suggests carbon and nitrogen have been maintained in the PTM during calcinations so as to induce the visible light activity. The PTM with 0.07 wt% graphene oxide dosage shows high efficiency for methyl orange (MO) decolorization under both full spectrum and visible light irradiation (λ >400 nm). Besides, the monolith remains intact and has good photocatalytic stability after four cyclic experiments.

“…Due to its commercial and technological potential, much work has doing on this material [9,10]. Titanium oxide involve in many applications such as water purification, lithium batteries, dielectric layer, gas sensing, solar cell, resistive switching etc [11][12][13][14][15][16][17]. Different method was adopted to increase their efficiency and applicability.…”

In this paper, structural and optical properties of undoped and sliver doped titanium dioxide film have been studied. By using Sol-gel method undoped and sliver doped titanium dioxide (TiO 2) thin film synthesis on FTO glass substrate. Sliver has been doped 3%,7%, concentration in titanium dioxide (TiO 2) .Different properties such as, crystal structure, phase identification, thickness, band gap, transmission and absorption spectrum have been studied using X-ray diffraction (XRD), Raman spectroscopy, UV/Vis spectrophotometry. The results showed that undoped and Ag doped TiO 2 thin film annealed at 450 o c had anatase phases and there is no Ag peaks in X-ray diffraction.
