Possible effect of carbon nanotube diameter on gas–surface interactions – The case of benzene, water, and n-pentane adsorption on SWCNTs at ultra-high vacuum conditions

Adsorption and reaction kinetics of small organic molecules on WS2 nanotubes: An ultra-high vacuum study

“…Interestingly, for all probe molecules, distinct structures appeared in TDS data obtained for WS 2 NT which suggest, in analogy to similar results obtained for carbon nanotubes (CNT) [14][15][16], that TDS allows for distinguishing adsorption of the probe molecule on internal, external, and groove sites of the NT. Unfortunately, reactive TDS experiments revealed only very small catalytic activity of the WS 2 NT towards HDS, although some activity was evident at amazingly low reaction temperatures.…”

“…As an example, Fig. 2III and IV shows n-pentane TDS of CNT supported on silica, collected in one of our prior projects [16]. The correspondence of the TDS data obtained on WS 2 and carbon NT is quite amazing.…”

Endohedral and exohedral complexes of 1‐benzene with carbon nanotubes and high‐density assembly of multiple benzenes inside of a carbon nanotube

“…Zarudnev et al studied the optimized structures and interaction energies for benzene with (10, 0) and (6, 6)CNTs. Komarneni et al used ultra‐high vacuum kinetic experiments to show that benzene interacts very strongly with the interior of CNTs. Milko et al studied the interaction of benzene inside zigzag CNT (n, 0) (n = 10‐18) by DFT and found that the benzene orientation between benzene and the CNT depended on the nanotube diameter.…”

Characterization of fundamental catalytic properties of MoS2/WS2 nanotubes and nanoclusters for desulfurization catalysis - a surface temperature study

“…We took the opportunity to acknowledge this DoE grant in three publications concerning gas-surface interactions with CNTs. [8][9][10] Later, a review and invited conference paper were also related to the CNT work. 11,12 However, the PI's group is not working on CNTs anymore.…”

“…In addition, collaborators at national laboratories and abroad were part of the projects, as proposed. More specifically, projects about HDS on MoS 2 and WS 2 inorganic fullerene-like nanoparticles, 1, 5 inorganic WS 2 nanotubes, 2 Mo and MoS 2 vapor-deposited nanoclusters, 3 modeling, 19 reviews/book chapter, 7,11 and side projects [8][9][10] have been conducted, as proposed, acknowledging solely (exception ref. 7 ) funding from this grant.…”
