Molecular hydrogen desorption from C70 encapsulated single-walled carbon nanotube (C70-peapod) has been investigated by Temperature-Programmed-Desorption (TPD) method. The single-walled carbon nanotube (SWNT) is in the spotlight recently due to reports of high-density hydrogen storage capability at moderate temperature. Here, we find that C 70-peapod loose hydrogen molecule at about 365 K and the NaOH treatment is crucial for the withdrawal of hydrogen at moderate temperature. This result fairly agrees with the previous our report in SWNT-bundles and C60-peapod.
