title: [Preparation of anatase-type TiO2 nanoparticals from Ti(SO4)2 solution under hydrothermal conditions and its photocatalytic performance].
abstract: Anatase-type TiO2 fine powders were synthesized under hydrothermal condition. The precursor was obtained via precipitation route using Ti(SO4)2. The characterization of the as-prepared sample was confirmed by TEM, XRD, UV-Vis and low temperature N2 adsorption measurements (BET). The photocatalytic activity was also investigated by the degradation of methyl orange solutions. The particles of the as-synthesized sample with narrow size distribution had an average diameter of about 24 nm. The specific BET surface area of the as-synthesized sample was about 56 m2 x g(-1), which is similar to the commercial TiO2 (P25). The prepared materials showed the similar photocatalytic activity when compared with the performance of commercial TiO2 (P25).
