Main scientific achievements 

The general patterns of energy transfer during the radiation-catalytic decomposition of substances such as water and hydrocarbons in the presence of nanosized metal and metal oxide catalysts have been studied. Thus, regularities and methods for controlling the processes of localization, recombination, and migration to the surface of nonequilibrium charge carriers, which play a key role in energy transport in radiation-catalytic processes in oxide catalysts, have been studied. The processes of formation and transport of nonequilibrium charge carriers to the surface of oxide catalyst particles under the action of gamma quanta are studied depending on the electrophysical properties of oxide compounds.

The radiation-catalytic activity of oxide catalysts has been studied depending on the composition, structure regularity, surface level, electrical properties, particle size, temperature, surface concentration of substances undergoing decomposition, and other characteristic parameters. Based on the results obtained, the basic principles of the mechanism of the radiation-catalytic action of oxide compounds and the scientific basis for choosing a catalyst for radiation-catalytic processes are disclosed. Based on the processes of decomposition of water, hydrocarbons, and the hydrocarbon-water system in the presence of oxide catalysts, effective methods for converting nuclear energy into the chemical energy of hydrogen have been determined.

In the presence of macro- and nanosized oxide catalysts, a comparative study of the kinetics of the processes of obtaining molecular hydrogen in the processes of radiation-heterogeneous and radiation-thermoheterogeneous decomposition of water was carried out. Based on the studies carried out, it was found that in the processes of radiation-heterogeneous and radiation-thermoheterogeneous decomposition of water in the presence of oxide catalysts with a particle size of R≤100 nm, a size effect is observed.
