The main activities of the laboratory are:
Promising directions in radiation-heterogeneous processes, the safety of nuclear reactors, and the study of the kinetics and mechanisms of metal oxidation processes under the influence of ionizing radiation and temperature in metal-water and metal-oxide-water systems in connection with the problems of hydrogen energy as an alternative energy source.

The main scientific results of the laboratory are:
     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 their composition, structure regularity, surface level, electrophysical 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 revealed. 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 conducted studies, the size effect in the processes of radiation heterogeneous and radiation thermoheterogeneous decomposition of water with the presence of oxide catalysts is observed at values of oxide sizes smaller than R≤100nm.
