Possible effect of carbon nanotube crystal structure on gas-surface interactions-the case of benzene, water and n-pentane adsorption ON SWCNTS.(COMMUNICATIONS--GRADUATE)
Thermal desorption spectroscopy (TDS) technique was used to investigate the effect of carbon nanotubes (CNT) crystal structure on adsorption kinetics of benzene, water, and n-pentane (1). The kinetics of adsorption of these molecules on single wall carbon nanotubes (SWCNTs) such as metallic CNTs (m-CNTs), semiconducting CNTs (s-CNTs, brand name CoMoCAT) and mixed CNTs(brand name HiPco) was studied. Scanning electron microscopy (SEM) images of these samples were obtained from Argonne national laboratory. Metallic CNTs were obtained from Clemson University.
Theoretically it is predicted that the binding energies increase with increase in CNT diameter for non covalent interactions. For covalent interactions it is predicted that the binding energies for adsorption on the inner CNT surface decrease with increase in CNT diameter and binding energies on the outer surface are smaller and independent of CNT diameter.

The diameters of CNTs used in this study decreases from 1.4 nm to 0.8 nm (m-CNTs > HiPco > s-CNTs). For all the CNT samples studied, four distinct features are found in each set of TDS curves. The peaks are labeled as A, B, C which refer to adsorption/desorption of probe molecule from internal, groove and external sites respectively. Peak D is an adsorption unspecific condensation peak. Interestingly for benzene, a trend of slightly decreasing binding energy with increasing CNT diameter ...
