AB  - Two series of nanocrystalline brookite-type powders have been synthesized by using combined sal gel hydrothermal method with titanium tetrachloride (TiCI4) as a precursor and hydrothermal temperature and reaction time varied in the range of 120-200 degrees C and 12-48 h, respectively. The effects of chosen synthesis parameters on structural, morphological and optical properties of synthesized powders have been investigated by the XRPD, SEM, EDS and BET measurements, as well Raman spectroscopy and spectroscopic ellipsometry. The XRPD results have shown that pure brookite phase, with mean crystallite size of -33 nm, has been obtained only in the sample synthesized at 200 degrees C, after 24 h of hydrothermal process. In all other samples anatase phase also appears, whereas rutile and sodium titanate phases have been noticed in the samples synthesized at lower temperatures. The presence of different titania phases has also been confirmed and analyzed by Raman scattering measurements. The SEM measurements have shown spindle-like particles in brookite-rich samples synthesized at 200 degrees C, whereas BET measurements have detected mesoporous structure in these samples. The properties of synthesized powders have been correlated to their photocatalytic efficiency, tested in degradation of alprazolam, one of the 5th generation benzodiazepines. The sample consisted of pure brookite has shown the highest efficiency in the photodegradation of alprazolam, practically equal to the activity of Degussa P25.

AB  - The subject of this research was utilization of concentrated solar radiation simulated with a sodium lamp SONT UV100, in lab condition, on removal of wastewater polluted by methyl-tertiary-butyl-ether (MTBE). The effects of titanium dioxide catalyst (commercial: Degussa P-25 (R) and 100% anatase, as well as sol-gel obtained titanium) on degradation of MTBE have been investigated. The processes were performed in slurry-catalyst batch circulating reactor. The photocatalytic degradation with different concentrations of TiO2 Degussa P-250 (R) catalyst: 2.5 g/L, 1 g/L and 0.50 g/L was studied. Our results showed that the MTBE degradation reached 50.80% in only 60 minutes, when 2.5 g/L of that catalyst was used. Also, the concentrated irradiation in combination with TiO2 (100% anatase) and FeCl3 caused high total degradation degree of 58.22%, for only 30 minutes. We synthesized titanium-dioxide, nanopowders doped with LaCl3 center dot 7H(2)O and FeCl3 center dot 6H(2)O, by sol-gel procedure. The highest degradation rate showed La-TiO2, for only 30 minutes and 48.60% of total degradation.
