Room Temperature Storage of Methane by Bamboo-Like Carbon Nanotubes

Single carbon nanotubes (CNTs) have the sorption states at around 200 K, and show the poor desorption characteristics at around 300 K. The bamboo-like CNTs, HP1050 and the ground HP1050 (HP-1050G), show the desorption peaks at around 100 K and 140 K, respectively. Furthermore, HP1050G has the sorption states at around 300 - 400 K. On the basis of the sorption process, the ground bamboo-like CNT has a possibility for application to the room temperature storage of methane, which has utility for energy technologies such as fuel cells.
