Thin films of TiO2 prepared on Ti by thermal oxidation in a wide range of temperatures (450°C - 900°C) were characterized by electrochemical impedance spectroscopy, potentiometry and amperometry. This material presents photoelectrochemical activity, which depends dramatically of the oxidation ...
4)25,26. In contrast, the Raman spectrum of TiO2-R displays slightly broadened peaks and reduced peak intensities due to a considerable number of defects within the lattice and on the surface27,28. Additionally, the vibrational modes of the anatase phase are observed in both TiO2 and TiO2-R...
Liquid-phase oxidants can be used to produce abundant oxygen-containing functional groups on the surface of carbon materials. (1) H2SO4. As a strong oxidizing acid, changes in the dosage of H2SO4 affect the number of oxygen-containing functional groups of carbon materials, while also ...
In Ti2AlC, an outer layer of T iO2 and an inner layer of A l2O3 had formed; T i3SiC2 had an outer layer of T iO2 and an inner layer of TiO2 and SiO2. The protective inner layers were dense, highly adhesive, crack-free, and exhibited high resist- ...

Electrochemical anodization process is...
In such a situation, the local matrix oxide thickness, hf,m, after N fatigue cycles will be (21)hf,m=N/nr,oxknr,oxΔt1/2 where Δt is cycle period, and nr,ox the number of cycles to fracture of the oxide scale (nr,ox<N). Using a statistical analysis of oxide thickness ...
2) represent highly resolved peaks at binding energy of 458.5 eV and split about 5.7 eV which is assigned to TiO bonds in TiO2 [16]. The second component at BE of 456.9 eV represents titanium ions in Ti2O3. Note the almost linear increase in the Ti3 + content with the increase of ...
Controlled vapor phase oxidation of titanium tetrachloride to manufacture titanium dioxide United States Patent 6387347 Abstract: A process for controlling the formation of TiO2particles in a multi-stage vapor-phase oxidation reactor wherein the process includes the steps of limiting the fraction of TiCl...
Titanium oxide nanotubes (TiO2nanotube, TNT) are nanostructured oxides having tubular shapes with almost no absorption in the visible light region (S. Iijima, Nature 354 (1991) 56-58—herein incorporated by reference in its entirety). UV light-sensitive chemical reactions occur at the surface of...
