Research has been carried out on the effect of adding isopropyl alcohol (IPA) formation nano titania. This study aims to determine IPA phase and particle size TiO2. In this study, titania was synthesized by hydrothermal method at a temperature 250oC with variety different additions, namely 0.2 ml, 0.4 0.6 0.8 ml. Samples were characterized using X-Ray Diffraction (XRD) Scanning Electron Microsc...

Lead hydroxyl compounds are known as rutile flotation of the traditional activated component, but the optimum pH range for flotation is 2–3 using styryl phosphoric acid (SPA) as collector, without lead hydroxyl compounds in slurry solution. In this study, Bi3+ ions as a novel activator was investigated. The results revealed that the presence of Bi3+ ions increased the surface potential, due to ...

Silica is the most abundant oxide component in the Earth mantle by weight, and stishovite, the rutile-structured (P4(2)/mnm) high-pressure phase with silica in six coordination by oxygen, is one of the main constituents of the basaltic layer of subducting slabs. It may also be present as a free phase in the lower mantle and at the core-mantle boundary. Pure stishovite undergoes a displacive pha...

Magnetic nanoparticles embedded into semiconductors have current perspectives for use in semiconducting spintronics. In this work, 40 keV Fe+ ions were implanted high fluences of (0.5 ÷ 1.5) × 1017 ion/cm2 an oxide semiconductor and single-crystalline TiO2 plates rutile structure with (100) or (001) face orientations. Microstructure, elemental-phase composition, magnetic properties the Fe-ion-i...

Direct splitting of pure water into hydrogen and oxygen was demonstrated using the rutile TiO2 powder under band gap irradiation. The successful water splitting results at least in part from the intrinsic properties of the rutile surface that is less sensitive to photoreduction of O2, a reverse reaction in water splitting.

Due to the unique properties and wide array of applications nanocrystalline materials based on titanium dioxide, study new synthesis approaches remains relevant. In this study, within framework extraction-pyrolytic method (EPM), we suggest using mixtures Ti- Eu-containing organic extracts valeric acid as precursors for fabrication TiO2-based powders with different Eu content: 0.5 mol%, 5 50 mol...

in this research fe-tio2 nanocomposites with different molar ratios of fe/ti were prepared as nano-photocatalyst using a modified sol-gel process at ambient temperature. crystallographic properties of nanocomposites were characterized by x-ray diffraction (xrd). surface morphology and mean particle size of nanocomposites were specified by field emission scanning electron microscopy (fesem) and ...

The electronic structure of nitrogen doped TiO2 prepared by annealing single crystal rutile (110) substrates in NH3 at elevated temperatures was investigated using high resolution X-ray photoelectron spectroscopy. NH3 treatment at 600 C introduced N into the TiO2 lattice without concomitant surface reduction of the rutile phase. This doping leads to bandgap narrowing associated with the appeara...
