Abstract
The surface and pore structure properties of the C60 and C60/C70 fullerene powders were studied by means of scanning electron microscopy, helium pycnometry, and 77.4 K nitrogen and argon adsorption. The pore structure of fullerene powders is macroporous and consists mainly of the voids between the fullerene aggregates. In the major part of the adsorption monolayer, both nitrogen and argon interactions with fullerenes are weaker than with graphite, possibly because of the reduction of the gas molecule−mirror image effect in the case of fullerenes. In Henry's law limit, however, nitrogen and argon adsorption on fullerenes is quantitatively similar to that on graphite because of the adsorption potential enhancement in the spaces between the surface fullerene molecules. In the multilayer regime, nitrogen adsorption on both fullerenes becomes similar to that on graphite. Both fullerenes behave similarly with respect to the adsorption of the studied gases.
