A single crystal of anatase TiO 2 was studied by Raman spectroscopy at quasi-hydrostatic pressures up to 70 GPa. The crystallinity of the sample shortens the pressure range of the transition to an α-PbO 2 structure to between 4.5 and 7 GPa. The resulting polycrystalline sample then transforms...
Size-Dependent Pressure-Induced Amorphization in Nanoscale TiO2 We investigated the size-dependent high-pressure phase transition behavior of nanocrystalline anatase TiO2 with synchrotron x-ray diffraction and Raman spectroscopy to 45聽GPa at ambient temperature. Pressure-induced amorphization result... V Sw...
Furthermore, it is demonstrated that the created TiO2 nanoparticles are chemically attached to the SWCNTs. Also, an important correlation between calculated TiO2 crystal size and the red shifts in the lowest Raman TiO2 (E.g.) predominate peak is reported. The synthesized TiO2-SWCNTs have ...
Finally, anatase TiO2 ultrathin nanobelts were obtained by a calcination of the hydrogen titanate ultrathin nanobelts. presents the most excellent properties in lithium storage11 and photocatalysis12. However, for lithium storage, anatase Li ion diffusion aTniOd 2psotoilrl suffers from low capacity ...
Thin TiO2 films were grown by atomic layer deposition on planar and porous substrates and characterized by Raman spectroscopy, x-ray diffraction, high resolution transmission electron microscopy, and spectroscopic ellipsometry. The growth conditions of anatase TiO2 are investigated, motivated by the applica...
The resulting mesoporous materials were characterized by powder X-ray diffraction(PXRD), transmission electron microscope(TEM), N_2 adsorption and Raman spectroscopy. All mesoporous TiO_2 has three-dimensional(3 D) ordered mesostructures with large Brunauer–Emmett–Teller(BET) surface area and narrow...
Raman spectra show that both types of nanocomposite photocatalysts share chemical bonds of TiO2 with the underlying CNT core. Furthermore, the spectra clearly indicate that the enhancement in photocatalytic activity was based on the difference in electronic properties of the CNTs. Arc-discharge ...
Synthesis of Nanoscale TiO2 and Study of the Effect of Their Crystal Structure on Single Cell Response To study the effect of nanoscale titanium dioxide (TiO2) on cell responses, we synthesized four modifications of the TiO2 (amorphous, anatase, brookite, an... ZR Ismagilov,NV Shikina,NA Maz...
Single crystals of titanium dioxide (TiO2), with highly reactive surfaces, show promise for energy and environmental applications. Unfortunately, the highly reactive surfaces tend to disappear during crystal growth as a result of the minimization of surf
