Abstract

The amount molecular hydrogen obtained from radiolysis process, it's formation rate and radiation-chemical yield are determined in the nano-SiO2/H2O system with a mass of m=0.2 g and d=20-60 nm particle size under the influence of gamma irradiation. In systems created by the adsorption of water on the surface of nano-SiO2 under the influence of gamma rays, the radiation-chemical yield of molecular hydrogen obtained from the decomposition of water was less than 0.36 molecules/(100 eV). This means that the surface density of the energy transfer centers on the surface of nano-SiO2 is very small. As the mass of water increases, the radiation of the nano-SiO2 emitted from the surface of the nanoparticles in the liquid space between the particles increases, and the radiation of the resulting molecular hydrogen also increases. However, the radiation-chemical yield of molecular hydrogen obtained from the decomposition of water was less than 0.36 molecules/(100 eV) in systems created by the adsorption of water on the surface of nano-SiO2 irradiated by gamma rays. This means that the surface density of the energy transfer centers on the surface of nano-SiO2 is very small. When the intergranular space is filled with water, the electrons emitted from the surface of the solid to the liquid phase and the radiation-chemical yield of salvaged electrons in liquid phase increases.
