Two types of plasma in contact with water were employed for the synthesis of mixed-phase TiO2 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.

等离子体与液体接触合成和表征氧化钛纳米颗粒

两种与水接触的等离子体被用于在液体中合成混合相 TiO2。这是具有金属阴极和水阳极以及水下等离子体的辉光放电。等离子体通过光发射光谱表征。为了检测液相中的活性物质，使用了化学剂量测定法。X 射线衍射、BET 分析和扫描电子显微镜用于表征获得的粉末。通过两种类型的等离子体获得的粉末是锐钛矿-金红石混合物。水下等离子体合成的样品中金红石含量较高。通过辉光放电获得的样品具有更发达的表面。提供了所得粉末对金属离子和有机染料的吸附能力数据。
