Adsorption Energy Distribution Functions for Single-Walled Carbon Nanotubes (SWCNT) |
| 초록 |
SWCNT was characterized by nitrogen adsorption/desorption isotherm, SEM, TEM, and Raman Spectroscopy. The equilibrium data of VOCs (Benzene, Toluene and m-Xylene) on SWCNT were measured at three different temperatures (303.15, 313.15 and 323.15 K) with pressures up to saturated pressure. The nitrogen and VOC isotherms exhibit typeⅡ and type I, respectively. The isotherm data were well fitted by Toth and UNILAN models. The isosteric heat of adsorption was calculated by Clausius-Clayperon equation. In addition, adsorption energy distribution functions were evaluated by generalized nonlinear regularization method. We found that SWCNT have energetically and structurally heterogeneous surfaces. |
