Titanium is a very important element for several industrial applications, being one of the ninth most abundant elements in the Earth’s crust (0.63% wt). In this work it will discuss the different mining and industrial activities involved in the production of titanium dioxide. The first step analyzed will treat about the beneficiation mining process of titanium mineral, and secondly, it will dis...

Mesoporous titanium dioxide materials were prepared using a nanocasting technique involving silica SBA-15 as the hard-template. At an optimal loading of titanium precursor, the hexagonal periodic array of pores in SBA-15 was retained. The phases of titanium dioxide could be easily varied by the number of impregnation cycles and the nature of titanium alkoxide employed. Low number of impregnatio...

Recently, titanium compounds with one-dimensional nanostructures, such as nanotubes and nanofibers, have recently attracted much attention. Among these 1-D compounds, nanotubes composed of titanium dioxide and titanate are now being studied actively. Titanium dioxide nanotubes can be synthesized using porous anodic alumina membranes (Imai et al., 1999; Yamanaka et al., 2004), organic molecules ...

in  this  reaserch,  photocatalyst  titanium  dioxide  was  doped  with silver  and modified  by  polyethylene  glycol  by  sol  gel method  and the  samples  were  characterized  by  x-ray  diffraction  (xrd)  and scanning  electron  microscopy  (sem).  the  purpose  of  the  present study  was  to  evaluate  the  photocatalytic  bactericidal  effects  of prepared nanocomposite on human pathog...

Molecular dynamics simulations of titanium dioxide nanoparticles in the three commonly occurring phases (anatase, brookite, and rutile) are reported. The structural properties inferred by simulated X-ray diffraction patterns of the nanoparticles were investigated. The titanium-oxygen bond length as a function of size, phase, and temperature was determined and was found to be dependent on the co...

abstract: background: release of volatile organic compounds (vocs) in industrial and urban area have adverse effects on human health and  environment. the aim of this study was removal of gaseous toluene, as the most of pollutants among vocs, by using of tio 2 nanoparticles coated on nickel foam substrate. methods: tio 2 nanoparticles prepared by sol gel method and coated on nickel foam. morpho...

background: benzene, toluene, ethyl benzene and xylene compounds (btex) are very dangerous in terms of health and environmental and have high toxicity in aquatic environment. the purpose of this study was to investigate the performance analysis of petroleum hydrocarbons xylene using solar radiation uv/tio2 method in industrial synthetic waste . methods: an experimental-interventional study was ...
