Two types of plasma in contact with water were employed for the synthesis of mixed-phase TiO

in a liquid. This is glow discharge with a metal cathode and water anode and the underwater plasma. The plasmas were characterized by the optical emission spectroscopy. To detect the reactive species in the liquid phase the chemical dosimetry was used. X-ray diffraction, BET analysis, and scanning electron microscopy were used to characterize obtained powders. The powders obtained by both types of plasma were an anatase-rutile mixture. The rutile content was higher in the sample, which synthesized by an underwater plasma. The sample obtained by the glow discharge had a more developed surface. The data on the sorption ability of the obtained powders for metal ions and organic dyes are presented. The advantages and limitations of using plasma in contact with water for the synthesis of titanium dioxide are considered.
