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 m 2·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).
