Using Fourier transform IR spectroscopy, the radiation-thermal decomposition of water in the nano-ZrO2 + nano-SiO2 + H2O system in the temperature range of T = 373-673 K under the influence of gamma-rays was studied. It is shown that water adsorption in zirconium and silicon nanooxides occurs by the molecular and dissociative mechanisms. Intermediate-active products of the radiation-heterogeneous decomposition of water-zirconium and silicon hydrides, hydroxyl groups-have been registered. The values of the velocities and radiation-chemical yields of molecular hydrogen during the radiolysis of water in the presence of nano-ZrO2 + nano-SiO2 mixtures were determined. It was revealed that the values of the velocities and radiation-chemical yields decrease on going from nano-ZrO2 to nano-SiO2. The stimulating role of radiation in the radiation-thermal decomposition of water in the temperature range of T = 373-673 K is shown.
