The project is aimed at solving the fundamental problem of managing the microstructural and functional properties of nanomaterials for catalysis and new energy sources. In the course of implementation, fundamental basic principles will be developed for the formation of nanoparticles of platinum group metals as a result of dispersion of a metal electrode under conditions of non-stationary electrolysis. The physicochemical regularities of the formation of noble metal nanoparticles during the electrochemical dispersion of metal electrodes (Pt, Rh, Pd) under the conditions of non-stationary electrolysis and the relationship between the electrolysis modes, microstructural and crystallographic characteristics of the formed dispersed products will be established, the principles of selecting the current parameters and electrolyte composition in in the process of dispersion of metal electrodes to ensure a directed change in the microstructural and crystallographic characteristics of noble metal nanoparticles, the effect of surfactants and their structure on the kinetics and mechanism of formation of dispersed products under conditions of non-stationary electrolysis has been studied, highly efficient and selective catalytic systems for electrocatalysis, in particular for processes , implemented in low-temperature fuel cells, correlations were established between the parameters of electrolysis, microstructural and crystal thallographic characteristics of the resulting dispersed products and their catalytic activity in processes implemented in low-temperature fuel cells. Conducting these studies will allow creating new approaches to controlling the functional properties of nanomaterials at the stage of their synthesis, which will ensure the environmental and economic feasibility of using new hydrogen technologies in the energy sector.
