Abstract | The structures of hydrogen hydrates with structure I (S I) and structure H (SH), are studied systematically with molecular dynamics simulation, and the stable structures of hydrogen hydrates are obtained. The structures shows the occupation of hydrogen: there are two H, molecules in a small cage and three H-2 molecules in a big cage in S I hydrate; there are two H-2 molecules in a small cage, two H-2 molecules in a middle cage, eleven H, molecules in a big cage in SH hydrate. The radial distribution function (RDF) for hydrogen-hydrogen in each cage of hydrogen hydrate is also investigated. Furthermore, the stable positions of hydrogen in each cage are determined. With these stable positions, the hydrogen storage capability of the hydrate is 5.085% (mass fraction) for S I and 6.467% (mass fraction) for SH. Compared to experiment, it is found that the hydrogen storage capacity of the SH hydrate with the stable structure is most excellent. |
