Materials with controllable multifunctional abilities for optical imaging (OI) and magnetic resonant imaging (MRI) that also can be used in photodynamic therapy are very interesting for future applications. Mesoporous TiO2 sub-micrometer particles are doped with gadolinium to improve photoluminescence functionality and spin relaxation for MRI, with the added benefit of enhanced generation of re...

Applying post thermal treatment on the doped TiO2 at high temperature is mostly regarded as an indispensable process, although it has negative effects on the photocatalytic activity of doped TiO2. Herein, we synthesized the N- and S-codoped TiO2 (NSTs) with an anatase phase using a simple solvothermal treatment and investigated their visible light photocatalytic activity associated with the the...

The structural parameters, band structures and density of states of anatase TiO2 co-doped with Cu and S were calculated by first-principles based on the density functional theory. The results indicate that the volumes of the co-doped TiO2 increase due to the lattice distortion. The calculated X-ray diffraction pattern shows that the crystal phase of TiO2 is still kept as anatase after Cu and S ...

Doping with other elements is one of the efficient ways to modify the physical and chemical properties of TiO2 nanomaterials. In the present work, anatase TiO2 nanofilms doped with Al and V elements were fabricated through anodic oxidation of Ti6Al4V alloy and further annealing treatment. Hydrogen sensing behavior of the crystallized Ti-Al-V-O nanofilms at various working temperatures was inves...

We prepared of electrodes that consist of TiO2 with addition of tin-doped indium oxide (ITO) or fluorine-doped tin oxide (FTO) nanoparticles and the application of such electrodes on dye-sensitized solar cell. As compared to TiO2 alone, the addition of ITO and FTO nanoparticles resulted in an efficiency improvement of ~ 20% up to ~ 54% for the TiO2ITO and TiO2-FTO systems, respectively. This im...

Decolorization of Reactive Black 5 (RB5) was investigated by heterogeneous photocatalysis using N-doped TiO2. TiO2 photocatalysts were synthesized means a sol-gel process. X-ray diffraction performed the characterization samples, scanning electron microscopy and photoelectron spectroscopy measurements. Photocatalytic activity samples assessed following decolorization degradation efficiency RB5....

In this research, undoped and doped (Fe, Ce, and Ag) antibacterial coatings of nanostructured TiO2 films were prepared by a sol-gel dip coating method. Doped and undoped TiO2 films were excited with ultraviolet (UV) radiation to improve their photo catalytic activity. The antibacterial activity against Staphylococcus Aureus bacteria was studied using an antibacterial–drop test and colony count ...

Density functional theory calculations were performed to investigate the interactions of NH3 molecules with TiO2/MoS2 nanocomposites in order to completely exploit the adsorption properties of these nanocomposites. Given the need to further comprehend the behavior of the NH3 molecules oriented between the TiO2 nanoparticle and MoS2 monolayer, we have geometrically optimized the complex systems ...

Amorphous titanium dioxide (TiO2) and gold (Au) doped TiO2-based surface acoustic wave (SAW) sensors have been investigated as hydrogen gas detectors. The nanocrystal-doped TiO2 films were synthesized through a sol-gel route, mixing a Ti-butoxide-based solution with diluted colloidal gold nanoparticles. The films were deposited via spin coating onto 64◦ YX LiNbO3 SAW transducers in a helium atm...
