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.展开更多

The absorption states exist at around 300 K as well as at around 100 K. X-ray photoelectron spectroscopy reveals that Ar2p shows the chemical shifts. These results suggest that Ar is in charge and it is in valence state, or gives the evidence of the chemical interaction.展开更多
