Spectroscopic Evidences for the Mixed Hydrogen Hydrate with the Various Guests in the Structure I and II |
| 초록 |
It was ascertained that hydrogen molecules were able to occupy the small cavities of structure I and II hydrate by using 1H solid-state NMR, Raman Spectroscopic and Gas Chromatographic methods. We confirmed that sI and sII hydrate contained 0.127 and 0.37 mol fraction of H2 when the pure ethane (sI) and propane (sII) hydrate was pressurized up to 120 bar with H2 at 270K. Occupancy ratios of each cage could be determined from NMR and Raman spectroscopy. They suggest that hydrogen molecules of 0.173 and 0.334 wt% could be contained in mixed hydrate lattice of sI and sII. These results show sII hydrate is more favorable than sI for applying to hydrogen storage. |
