英文摘要: Information of adsorption and diffusion in nanoporous material is helpful to fundamentally understand nanocatalysis and gas sensors. In this work, the adsorption process of benzene in double-walled carbon nanotubes (DWNTs) at the very earliest stages was directly monitored for the first time by using in situ solid-state C-13 NMR. The results indicate that benzenes in and out of DWNTs can be conveniently distinguished by C-13 MAS NMR. The kinetics of the adsorption process was obtained by integrating the C-13 peaks as a function of adsorption time. The kinetic could be interpreted with a model of opposing adsorption-desorption process and the kinetic curves could be satisfyingly fitted by an exponential function.
