초록
The high-pressure H2 sorption isotherms of polyaniline-vanadium pentoxide nanocomposites (PANI-VONC) have been performed at liquid nitrogen temperature. A large increment of hydrogen storage capacity occurs in PANI-VONC (~1.8혻wt%) in contrast to that in pristine vanadium pentoxide (~0.2혻wt%) and in non-treated polyaniline (~0.2혻wt%). It is considered that the reason for the enhancement of hydrogen storage in PANI-VONC is the intercalation of polyaniline (PANI) into the vanadium pentoxide layers. The intercalation of PANI decreases the interlayer distance from 1.1혻nm between vanadium pentoxide layers to 0.72혻nm between vanadium pentoxide layer and polyaniline layer. © 2009 Professor T.
