| Research Abstract |
Condensates (Ne, Ar and Kr) in mesopores have been investigated by adsorption isotherm measurements over the range of temperatures from 16-127 K. We have used mesoporous silica SBA-15 of which the pore surface is uniformly covered with a few carbon layers for the experiments (C/SBA-15, pore width: 5.5 nm). The pressure-temperature (P-T) phase diagrams of the confined Ne, Ar and Kr in C/SBA-15 have been established with the experimental adsorption data. The P-T phase diagram of confined Ar, which is reduced by the critical pressure and temperature of the bulk fluid, is in good agreement with that of confined Kr, suggesting that the confined classical fluids obey the principle of corresponding states. On the other hand, the reduced P-T phase diagram of confined Ne does not coincide with those of the classical confined fluids, and shows higher freezing point than the classical fluids, indicating that it does not follow the principle of corresponding states. This suggests that quantum effects can not be neglected even for confined Ne.
