The decoration of a copper cluster on the anatase phase (101)-TiO2 surface to increase reduction CO2 has gained significant interest and potential trigger sustainable solar-fuel-based economy.

TiO2 is known as one of the excellent and demanded materials for its wide applications. In this paper, the growth of TiO2 nanotube arrays by using simple and inexpensive electrochemical anodizing of a titanium foil is presented. The vertically oriented TiO2 nanotube arrays were prepared in electrolyte solution of 3 wt % HF (40%) and dimethyl sulfoxide (DMSO) at constant DC voltage of 30 V for 1...

In this study, different samples of Niobium and Vanadium co-doped titania  thin films (5-10-15 mol% Nb and 5-10-15 mol% V) were prepared via sol−gel dip coating method, using niobium chloride as niobium precursor, ammonium metavanadate as vanadium precursor, and titanium (IV) butoxide (TBT) as titanium precursor. The effects of doping amount on the structural, optical, and photo-catalytic prope...

TiO2-SiO2 photocatalytic nanostructure film on windshield for self-cleaning purposes was prepared via sol–gel dip-coating method. TiO2 films were prepared on automotive glass pre-coated with a SiO2 layer by a dip-coating method followed by annealing at 500 °C for 30min. The films were characterized using X-ray diffraction XRD and scanning electron microscopy SEM, FE-SEM techniques. The TiO2-SiO...

2,4-dichlorophenoxyacetic acid (2,4-D) is well known as inexpensive herbicides, but it can give rise to undesirable pollution. The objective of this investigation was to compare effectivity of photolysis, sonolysis and ozonolysis methods for degradation of 2,4-D. Photolysis method were performed using an irradiation of UV light λ= 365 nm, sonolysis using an ultrasound with output power of 60 Wa...

A new model of Li intercalation into rutile and anatase structured titania has been developed from first principles calculations. The model includes both thermodynamic and kinetic effects and explains the observed differences in intercalation behavior and their temperature dependence. The important role of strong local deformations of the lattice and elastic screening of interlithium interactio...

Nanocrystalline titanium dioxide powder is characterized for phase analysis as well as particle size and its distribution by x-ray diffraction and small angle neutron scattering measurements. Analysis of the SANS data in the momentum transfer range q = 0.1 1.8 nm reveals an average particle size of 24.82 nm in good agreement with the particle size determined earlier by transmission electron mic...

The physicochemical properties of titanium dioxide (TiO2) depend strongly on the crystal structure. Compared to anatase, rutile TiO2 has a smaller bandgap, higher dielectric constant, and refractive index, which are desired for thin films in many photonic applications. Unfortunately, fabrication usually requires temperatures that too high (>400 °C, often even 600–800 °C) applications involving,...

Titanium dioxide (TiO 2 ) nanotubes array with the length of 16 μm and outer diameter 100 nm were synthesized by anodic oxidation titanium foil in an electrolyte solution containing a fluorine-containing ethylene glycol. The selected synthesis conditions make it possible to separate nanotubular from study as homogeneous functional material. performed scanning electron microscopy Brunauer--Emmet...
