| الوصف: | 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 γ-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. |
