AB  - TiO2 nanopowders were produced by sol-gel technique using TiCl4 as a starting material. For the preparation of crystalline anatase with developed surface area, this aqueous solution has been mixed with 0.05 M or 0.07 M (NH4)(2)SO4 solution in a temperature-controlled bath. The pH values of the suspension were 7, 8 or 9. According to the x-ray diffraction (XRD) analysis the anatase crystallite sizes were about 12 nm, which coincided with the average particle size revealed by scanning electron microscopy (SEM). The Raman scattering measurements have shown the presence of a small amount of highly disordered brookite phase in addition to dominant anatase phase with similar nanostructure in all synthesized powders. BET measurements revealed that all synthesized catalysts were fully mesoporous, except the sample synthesized with 0.07 M (NH4)(2)SO4 at pH=9, which had small amount of micropores. The photocatalytic degradation of herbicide Clomazone was carried out for both the pure active substance and as the commercial product (GAMIT 4-EC) under UV irradiation. The best photocatalytic efficiency was obtained for the catalyst with the largest specific surface area, confirming this parameter as crucial for enhanced photocatalytic degradation of the pure active substance and commercial product of herbicide Clomazone.

AB  - TiO2 nanopowders were produced by sol-gel technique using TiCl4 as the starting
material. For the preparation of anatase crystalline, this aqueous solution was the mixed with
0.05 M and 0.07 M (NH4)2SO4 solution in a temperature-controlled bath. PH values of the
solutions were 7, 8 and 9, respectively. Structural, morphological and surface properties of
synthesized TiO2 nanopowders were investigated by XRD, SEM, and BET measurements.
The crystallite sizes determined by XRD measurements had range about 12 nm, and this was
confirmed by SEM. The photocatalytic degradation of the pure active substance and commercial product (GAMIT 4-EC) of herbicide clomazone (0.05 mM) in aqueous
suspensions of synthesized and commercial (Degussa P25) TiO2 were examined under UV
radiation. In all experiments the concentration of the catalyst was 0.50 mg mL-1. BET
measurements revealed that all synthesized catalyst had mesoporous structure, except the
sample synthesized with 0.07 M (NH4)2SO4 and at pH of solution 9 that had small amount of
micropores. This sample had the best photocatalytic properties, even better than commercial
Degussa P25, and the reason of that is rather the biggest porosity than the combination of
micro- and mesoporosity.
