INVESTIGATION FOR HYDROGEN STORAGE MECHANISM OF SINGLE-WALL NANOTUBE

On the basis of the fact that single wall nanotube in the ambience of hydrogen is considered grand canonical assemblage , two order parameters are defined and a theory of hydrogen storage mechanism is proposed. The authors suggest that the reasons for the large hydrogen storage capacity of the nanotube can be ascribed to the following aspects: decomposition of hydrogen may enhance the pressure, the correlated interaction between hydrogen molecules and atoms will give rise to the decompression, resulting in the condensation of the gas and the increase of the hydrogen storage as well.
