TiO(2) is one of the most studied compounds in materials science. Owing to some outstanding properties it is used for instance in photocatalysis, dye-sensitized solar cells, and biomedical devices. In 1999, first reports showed the feasibility to grow highly ordered arrays of TiO(2) nanotubes by a simple but optimized electrochemical anodization of a titanium metal sheet. This finding stimulated intense research activities that focused on growth, modification, properties, and applications of these one-dimensional nanostructures. This review attempts to cover all these aspects, including underlying principles and key functional features of TiO(2), in a comprehensive way and also indicates potential future directions of the field.

“…The properties of particles change as their size approaches the nanoscale which in turn provides a large surface area. A variety of nanoparticles like SiO 2 , Cu, TiO 2 , ZrO 2 , BaTiO 3 , BaZrO 3 , LiNbO 3 and Fe 2 O 3 are reported in literature (Finnie et al 2007;Qui et al 1999;Li and Wang 1999;Sundaram et al 2007;Niederberger et al 2004;Kang et al 1996). The two main types of the oxides of iron, i.e., magnetite Fe 3 O 4 and maghemite Fe 2 O 3 are considered to be of great interest due to their paramagnetic properties and thus are used in many fields.…”

We have tested modified hydrolysis method for the preparation of a-Fe 2 O 3 nanoparticles. The particles after synthesis were applied for a series of physicochemical techniques. Iron chloride was used as a precursor material. The particle size distribution was determined using zeta sizer and scanning electron microscopy. The surface area and the morphology of the particles vary by changing the concentration of the precursor material. The size of nanoparticles varies from 10 to 90 nm. The particles having size of 23 ± 1 nm were separated out from the solution and their size remains almost the same even after one month. Energy dispersive X-ray analysis (EDX) of Fe 2 O 3 nanoparticles confirms the purity of the desired material. The weight loss of the particles with respect to the temperature was studied by thermogravimetric and differential thermogravimetric (TG/DTG) analysis. X-ray diffraction (XRD) has been employed to study the crystallinity of the particles.

“…TiO 2 particles prepared in these systems had average size of about 5 nm and a narrow size distribution. TEM, DTA-TGA, and Raman spectroscopy studies indicate that their phase transition behavior is close to that of the dry gel prepared by the sol-gel method (Li & Wang, 1999).…”
