“…Therefore, these types of materials are widely used in different fields of science and technology. One of these areas of application is the method of obtaining molecular hydrogen from the decomposition of water used for the transition from nuclear energy to hydrogen energy using nanoscale and high surface area catalysts [3][4][5][6][7][8].Three of these methods are preferred. The process is carried out both at the catalyst water boundary and with the solvated electrons emitted from the catalyst surface into the waterin the system of nanoscale catalysts suspended in water at room temperature; in the third method, the radiation-thermocatalytic processes of nanoparticles in contact with water vapor under the influence of temperature occur as the sum of two independent thermocatalytic and radiation-catalytic processes.…”

The physicalchemistry properties and crystal structure of were nano-ZrO2+3mol.%Y2O3 determined. The kinetics of the formation of H2 as a result of the decomposition of H2O on the surface of nano-ZrO2+3mol.%Y2O3 was studied. Effects of adsorption and desorption process on ZrO2+3 mol.%Y2O3 nanoparticles were studied at different (T=400÷10000C) temperature. The study of H2 in thermal processes at nano-ZrO2+3 mol.%Y2O3 system increased. Such an increase in H2 generation in comparison with a pure H2O as thermal processes had formedactive centers for H2O decomposition on the surface of the catalyst at the expense of δ-electrons emitted on the surface of nano-ZrO2+3 mol.%Y2O3. This showed that the dimensions of the studied nanoscale particles systems are comparable to the free running distance of energy carriers generated by of nano-ZrO2+3 mol.%Y2O3 as a result of thermal processes. These results are promising for hydrogen generation by waer spliting in near future.

The study of physicochemical properties of nano-ZrO2+3mol.%Y2O3 was determined. The X-ray diffraction spectrum of the nano-ZrO2 and system nano-ZrO2+3 mol.%Y2O3 compound was drawn by the Ritveld method and the crystal structure was determined at different temperatures (T = 373, 473, 573, 673 K) and under normal conditions. The energy of the arrangement of H2 as a result of the decay of H2O, on the surface of nano-ZrO2+3mol.%Y2O3 was considered. Impacts of adsorption and desorption preparation of ZrO2+3mol.%Y2O3 nanoparticles were considered at diverse (T = 373, 473, 573, 673 K) temperatures. The thought of H2 in warm forms at nano-ZrO2+3mol.%Y2O3 framework expanded. This tells about hydrogen era by water part in close future. Nano-ZrO2 and system nano-ZrO2+3mol.%Y2O3 with the temperature range of T = 373, 473, 573, 673 K have been studied by SEM analysis. These results are promising of hydrogen generation by water splitting in near future.

“…Therefore, the connection between the transmitted excitation energy (Eexc) and the communication energy must satisfy the Eexc≥Erab condition. The electrons radiated from the surface of the strong to fluid stage slowly lose their active vitality by versatile and inelastic collisions in water and initially changed over into warm electrons, and after that can rescue within the water [24][25][26][27][28][29][30][31]:…”

In this research, the radiation-heterogeneous processes of water decomposition on the surface of zirconium dioxide nanoparticles (n-ZrO2) were studied. The kinetics of buildup of molecular hydrogen during the radiolytic processes of water decomposition was also examined. The production of H2 and H2O2 through water radiolysis was investigated to develop a computational model and disclose the kinetic behavior of water radiolysis. The enthalpy of ZrO2 nanoparticles was studied at the temperature range T=1200-2900 K, in which ZrO2 nanoparticles has a two-phase transition. Some of the electrons were transported to the surface of the nanoparticles during the physical and physicochemical stages of the process and emitted into the water. At the same time, the migration of energy carriers in radioactively active oxide compounds changed at different intervals depending on the composition, structural stability, and electro-physical properties of the oxides.
