Registration Date 02-02-2022 Organization National Technical University "Kharkiv Polytechnic Institute" popup.description2  The object of research is physicochemical processes of formation of nanostructured heteroxide composites and coatings with high catalytic activity for catalytic converters of dual purpose. The aim of the work is to develop physicochemical bases for the synthesis of nanostructured metal oxide composites as catalytic materials for converters of reagent-free disposal of natural, synthetic and man-made toxicants, designed for filter ventilation systems of stationary facilities and vehicles, reduction of toxic emissions also gaining new knowledge for the development of high technologies in Ukraine. Research methods - linear and cyclic voltammetry, X-ray fluorescence and X-ray diffraction phase analysis, methods of polarization resistance, impedance spectroscopy and gravimetry, scanning electron microscopy, vibration magnetometry. A methodology for the synthesis of metal oxide composites and multicomponent alloys with a synergistic level of functional properties by means of programmable electrolysis and nanoengineering with the implementation of the principles of "bottom-up" for alloying elements and intermediates. Regularities of inversion of structural matrices of metal oxide composites with the use of programmable electrolysis, which allows to form nanoscale multicomponent coatings within a wide range of components. The catalytic activity of metal oxide composites in redox reactions based on quantitative consideration of energy factors of elementary acts, which are subject to the course of reactions, the synergistic nature of composite materials and scientific principles of self-organization of oxide structures is predicted.
