ナトリウム-水反応の混相領域への量子分子動力学解析の適用.

We compared the sodium-water reaction in vapor sodium phase at 1273 K with that in the sodium/metal multiphase domain by applying the accelerated quantum chemical molecular dynamics method. Considering the gas/liquid mixture condition on the sodium-water interface as well as the solid reaction products such as sodium oxides, the sodium-water reaction itself is regarded as multiphase reaction. In case of the water adsorption over the vapor sodium phase, sodium atoms lost electrons, and desorbed as hydrogen molecule. In case of the sodium vapor over the transition metal titanium surface, a pair of hydrogen atom was produced. [ABSTRACT FROM AUTHOR]
