Hydrogen Gas Evolution From Water Dispersing Nanoparticles Irradiated With Gamma-Ray

Hydrogen Gas Generation from the Water by Gamma-Ray Radiolysis with Pre-Irradiated Silica Nanoparticles Dispersing

“…The layout of experimental setup was described elsewhere. 1) A part of the gas in the head space of the vial was sampled by using a syringe with a volume of 0.5 ml, and the amount of hydrogen gas in it was measured with a gas chromatograph (Shimadzu Corp. GC-8A) with molecular sieve 5A column (3 mm i. d. and 3 m length) and a thermal conductivity detector. The total amount of the hydrogen gas in the head space of the vial was evaluated from the ratio of the volume for sampling in the head space.…”

“…In the case when the oxide nanoparticles such as SiO 2 , TiO 2 , Al 2 O 3 or ZrO 2 disperse in the water the enhancement of the hydrogen gas generation has been observed. [1][2][3][4][5][6] However, the cause of the enhancement is not obvious so far. This would be due to the fact that the irradiation effects on the water and the nanoparticles have not been distinguished.…”

Study of Nano-Al2O3 + Nano-SiO2 + H2O System by Fourier-IRSpectroscopy Method

“…In the process of radiolysis of water, various methods are used to determine the mechanism of radiationcatalytic action of oxide catalysts, as well as spectroscopic methods [4][5][6][7]. Radiation-thermal decomposition of water in many nanooxide + water systems has been studied using Fourier-IR spectroscopy [8][9][10]. However, there is almost no information in the literature on the radiation-thermal decomposition of water in the nano-Al 2 O 3 + nano-SiO 2 + H 2 O system.…”
