The impact of silicon mass on the radiolysis process occurring under the influence of γ-quanta on nano-Si/H₂O suspension system

The amount, formation rate, and radiation-chemical yield of molecular hydrogen, obtained from water radiolysis process within the system under the influence of γ-quanta (⁶⁰Co, P=22 rad/sec, T=300K), have been defined by maintaining the water volume constant (V=6 ml) and by changing the silica mass (m_Si=0.0 (pure water), 0.0025, 0.005, 0.01, 0.015 0.02, 0.03, 0.04, 0.06, 0.12 g) in nano-Si/H₂O system with d=50 nm particle size. It was found that the amount, formation rate and radiation-chemical yield of molecular hydrogen, defined according to the overall system from radiation-heterogeneous transformation of water, increase directly proportional to the silica mass in the m_Si≤0.02 g values of nano-silicon mass added to the water, but in m_Si>0,02 g values, the inclination angle decreases. The formation rate and radiation-chemical yield of molecular hydrogen, defined according to nano-silica, do not change at m_Si≤0.02 g, but there is observed a decrease at m_Si>0.02 g. The maximum radiation-chemical yield of molecular hydrogen, determined according to the overall system, got the value of 10.9; but according to the nano-silicon, the value of 1788 molecules/100 eV.
