UNLABELLED BACKGROUND CuO-TiO2 nanosheets (NSs), a kind of nanomaterials is one of the most attracting class of transition doped semiconductor materials due to its interesting and important optical, electrical, and structural properties and has many technical applications, such as in metal ions detection, photocatalysis, Chemi-sensors, bio-sensors, solar cells and so on. In this paper the sy...

New assemblies constituted by a microporous matrix of mordenite (MOR) zeolite on which TiO2 nanoclusters are deposited were synthesized using ionic oxalate complexes and TiCl3 titanium precursors. The samples were used to investigate the transfer of electrons produced by spontaneous or photo-induced ionization of a guest molecule (t-stilbene, t-St) occluded in the porous volume towards the cond...

The results of this study indicate that titanium dioxide nanoparticles (nano-TiO2) possess adsorptive, photocatalytic, bactericidal, virucidal and fungicidal properties, which are used in antibacterial coating, for air water disinfection. In parallel with studies the physicochemical characteristics dioxide, its toxicological assessment was carried out to prevent possible harmful effects on huma...

In this paper, we report the comparison between TiO2 nanoparticles prepared via two different routes; i) via sol-gel route and ii) by hydrothermal method. It was found that when prepared under the same ambient conditions viz temperature, pressure etc. and keeping all the parameters same viz precursors, mole ratio, solvent etc; the nanoparticles prepared via sol-gel route were highly crystalline...

Nanoparticles of titanium dioxide doped with Fe2+ ions have been synthesized via sol-gel technique using Titanium tetraisopropoxide (TTIP) and ferrous sulphate as a precursors. The synthesized nanopowders were characterized by Powder X-ray Diffraction (PXRD), Scanning Electron Microscope (SEM), Fourier Transform Infrared (FTIR), Ultraviolet Visible (UV-Vis) and Photoluminescence (PL) Spectrosco...

Hydroxyapatite/titania nanocomposites (TiHAp) were synthesized from a mixture of a titanium alkoxide solution and dissolution products of a Moroccan natural phosphate. The simultaneous gelation and precipitation processes occurring at room temperature led to the formation of TiHAp nanocomposites. X-ray diffraction results indicated that hydroxyapatite and anatase (TiO2) were the major crystalli...

TiO2-based nanofibers were synthesized using a sol-gel method and electrospinning technique. The as-spun composite fibers were heat-treated at different temperatures (500°C, 550°C, 600°C, and 650°C) and atmospheres (ammonia and nitrogen) for 4 h. The fibers had diameters of 50 to 200 nm and mainly featured anatase and rutile phases. The anatase phase decreased and the rutile phase increased wit...

Alumina-titania coatings are widely used in industry for wear, abrasion or corrosion protection components. Such layers are commonly deposited by atmospheric plasma spraying (APS) using powder as feedstock. In this study, both Al2O3 and Al2O3-13 wt% TiO2 coatings were deposited on austenitic stainless steel coupons by suspension plasma spraying (SPS). Two commercial suspensions of nanosized Al2...

Vibrational sum frequency generation (SFG) spectroscopy has been utilized to study the spatial orientation and alignment of Re(CO)3Cl(dcbpy) (dcbpy = 4,4′-dicarboxy2,2′-bipyridine) (or ReC0A) on the (001) and (110) surfaces of rutile single-crystalline TiO2. The SFG intensity of the CO stretching modes shows an isotropic distribution on the (001) surface and an anisotropic distribution on the (...

We report the highly stable supercapacitive performance of one-dimensional (1D) nanoneedles of brookite (b) TiO2 synthesized on a conducting glass substrate. The 1D b-TiO2 nanoneedles synthesized over a large area array utilizing hot-filament metal vapor deposition (HFMVD) were 24–26 nm wide, 650 nm long and tapered in a downward direction. X-ray photoemission spectroscopy (XPS) revealed their ...
