Object of the investigation - processes for creating TiOx-Pt and TiOx-Pd composites. Aim - identification of scientific and experimental bases of combined electrochemical-pyrolytic creation of composites of the TiOx-Pt system for the creation of a transition layer of the Ti/PbO2 anode and TiOx-Pd electrodes for cathodic dehydrohalogenation of organic compounds and synthesis of hydrogen peroxide. Research methods - voltamperometry, scanning electron microscopy, X-ray diffraction. As a result of the work, a set of new experimental data on the synthesis of titanium suboxides by electrochemical reduction of TiO2 nanotubes was obtained; A set of new experimental data on the influence of electrolyte composition, cathode current density and duration of electrolysis on the physicochemical and semiconductor properties of materials based on titanium suboxides. The general regularities of electrodeposition of thin non-continuous layers of platinum and palladium on the surface of titanium suboxides have been determined. A set of new experimental data on the effect of the amount of platinum and palladium on the oxide surface, temperature and duration of heat treatment on the composition, physicochemical and semiconductor properties, as well as electrocatalytic activity and stability of composites of this type has been obtained. A mechanism for introducing platinum group metals into the oxide matrix of an electrocatalyst has been invented. Area of application: C 20.13 Production of other main inorganic chemicals; М 72.19 Research and experimental development in the field of humanitarian and technical sciences.
