abstract
titanium dioxide nanocrystals were synthesized by sol-gel method at room temperature. titanium isoprophoxide and absolute ethanol were used as precursors to prepare the sol. the ph of the solution was adjusted by adding nitric acid and sodium hydroxide solution. the prepared tio2 nanocrystals were annealed at 325°c, 425°c and 525°c respectively. the effect of ph on the surface morphology and structural properties of tio2 nanocrystals were studied.

full textThe effect of molar ratio on structural and magnetic properties of BaFe12O19 nanoparticles prepared by sol-gel auto-combustion method
Nanocrystalline particles of barium hexaferrite has been prepared by the sol–gel auto- combustion method using iron and barium nitrate with a Ba:Fe molar ratio of 1:10. The effect of fuel such as citric acid and aspartic acid was investigated on the structure and magnetic properties of nanoparticles. The results revealed that the formation of barium hexaferritefine particles is influenced by mo...

full textEffect of hydrolysis rate on the properties of TiO2-CNT nanocomposite powder prepared by sol-gel method
In this study, TiO2-10%wt. carbon nanotube (CNT) nanocomposite powders were synthesized by sol-gel method at various hydrolysis rate affected by different reaction agents of acetyl acetone and benzyl alcohol. Crystallization of TiO2 was then achieved through calcination at 400 °C. The properties of nanocomposite powder investigated by scanning electron microscopy, X-ray diffraction and diffuse ...
full textCharacterization of Structural, Optical and Hydrophilicity properties of TiO2 Nano-Powder Synthesized by Sol-Gel Method
In this paper, titanium dioxide nano-particles were synthesized by sol-gel method in acidic atmosphere. The microstructure, morphology, optical band gap, and hydrophilicity of the sample were studied. Optical band gap of titanium dioxide was probed via Diffuse Reflectance Spectra (DRS) and contact angle (CA) was measured to investigate surface activity. XRD analysis was used to study crys...
full textCharacterization of Zr-doped TiO2 nanocrystals prepared by a nonhydrolytic sol-gel method at high temperatures.
Highly crystalline and surface-modified Zr-doped TiO(2) nanorods were successfully prepared using a nonhydrolytic sol-gel method that involves the condensation of metal halides with alkoxides in anhydrous trioctylphosphine oxide (TOPO) at either 320 or 400 degrees C. In addition, the interaction of the cross-condensation between the Ti and Zr species was studied by characterizing the morphologi...
