A comparative study of the scope and surface properties of alumina (Al 2 O 3 ) and titanium dioxide (TiO 2 ) nanoparticles, synthesized using different methods, was carried out using Fourier-transform infrared spectroscopy (FTIR), ultraviolet UV-Vis diffuse reflection spectroscopy (UV-Vis DRS), and Raman spectroscopy, as well as X-ray diffraction methods. It is shown that the differences in the synthesis methods can change the surface properties of the nanoparticles, while maintaining the phase composition of the material. The nanoparticles of each material are shown to exhibit unexpected properties. In particular, the special luminescence characteristics of TiO 2 , a photon-energy shift from the rutile region into that region typical for the anatase, and a significant difference in the Lewis center concentration values for the alumina -phase were observed. This variation in the properties indicates the necessity to involve a wider range of analysis techniques and the importance of precisely characterizing the surface properties. To identify those nanoparticle functional properties that determine their interactions with other materials, a comprehensive study of their phase compositions and surface properties must be completed.

“…Takahashi et al [98] were the first to prepare almost pure brookite films by vapor phase decomposition of tert-butyl titanate. Evidence for the formation of a brookite layer as an intermediate of the anatase/rutile transition was also observed by in situ Raman spectroscopybafter controlled oxidation of a Ti electrode in KOH electrolyte [99,100].…”

Brookite, the Least Known TiO2 Photocatalyst

Abstract:Brookite is the least studied TiO 2 photocatalyst due to the difficulties usually encountered in order to obtain it as a pure phase. In this review, a comprehensive survey of the different methods available for preparing brookite powders and films is reported. Attention has been paid both to the most traditional methods, such as hydrothermal processes at high temperatures and pressures, and to environmentally benign syntheses using water soluble compounds and water as the solvent. Papers reporting the photocatalytic activity of pure and brookite-based samples have been reviewed.

Improved bonding strength between TiO₂ film and Ti substrate by microarc oxidation

Titanium (Ti) and its alloys have proved to be very suitable materials for load-bearing bioimplant applications. Unfortunately, Ti and its alloys exhibit poor osteoinductive properties like most metals. This drawback was recently addressed by modified titania (TiO 2 ). However, the bonding strength between TiO 2 and substrate is not very strong. Therefore, mechanical properties and biochemical stability are very important.Many techniques have been investigated for modifying the TiO 2 layer. Microarc oxidation (MAO) represents a relatively new surface modification technique where thick, hard and anticorrosive oxide coatings can be easily and cost-effectively fabricated. In this study, various chemicals were used as the electrolyte for MAO. Hydroxyapatite (HA) suspension was prepared by dispersing HA powder in distilled water and adjusting the pH in the range of 4-11.Bonding strength between TiO 2 film and substrate was determined by modified ASTM C-633 and the ability to form apatite was confirmed after MAO, by soaking in simulated body fluid (SBF). The bonding strength decreased when the electrolyte was changed, but increased with increasing voltage. Bioactivity was only present in NaOH-treated specimens.
