FOURIER-TRANSFORM IR SPECTROSCOPY OF THE NANO-ZrO2+NANO-SiO2+H2O SYSTEMS EXPOSED TO GAMMA-RADIATION
Abstract
The radiation decomposition of water in a nano-ZrO2+nano-SiO2+H2O system at T = 300 K under the action of gamma-radiation is studied by Fourier-transform IR spectroscopy. It is shown, that water adsorption in Zr and Si nanooxides happens by the molecular and dissociative mechanisms. Intermediate active products of the radiation-heterogeneous water decomposition are registered including Zr and Si hydrides, hydroxide groups. It is shown that changes in the ratio of ZrO2 and SiO2 nanopowders result in a decrease of the radiation-catalytic activity comparing to the initial ZrO2.
