Head Velichenko Oleksandr B., Доктор хімічних наук Registration Date 25-02-2025 Organization Ukrainian State University of Science and Technologies popup.description1 Development of theoretical and experimental principles of electrochemical creation of materials based on modified titanium suboxides for photo- and electrocatalysis. popup.description2 The object of investigation is the oxide catalysts based on titanium suboxides modified with platinum group metals. Work concerns on the development of scientific and experimental foundations for the electrochemical and/or combined electrochemical-pyrolytic modification of titanium suboxides with platinum group metals. Identification of materials, investigation of their physicochemical and semiconductor properties. Determination of the effect of modification on the composition, physicochemical properties, and electrochemical characteristics of the materials. Research methods – stationary and cyclic voltammetry, chronoamperometry, electrochemical impedance spectroscopy, scanning electron microscopy, X-ray photoelectron spectroscopy, X-ray diffraction. The regularities of electrodeposition of thin discontinuous layers of platinum group metals on the surface of titanium suboxides have been established. A set of new experimental data was obtained regarding the influence of the amount of platinum group metals on the oxide surface, as well as the temperature and duration of heat treatment, on the composition, physicochemical, and electrochemical properties of the resulting composite materials. The materials were identified, their composition determined, and the morphology, texture, semiconductor, and electrochemical properties of the modified coatings were studied. Experimental foundations for the creation of modified materials of various compositions and the general mechanism of incorporation of platinum group metals into the suboxide matrix of the electrocatalyst were established. Areas of application: C 20.13 Manufacture of other basic inorganic chemicals; M 72.19 Research and experimental development on natural sciences and engineering.
