Estudio comparativo de la adsorción de nitrógeno sobre nanoconos y nanotubos de carbón

We studied the adsorption of nitrogen on nanostructures of carbon with cylindrical (nanotubes) and conical (nanocones) geometries, when their ends are open or closed. It was found that the adsorption capacity of open nanotubes is more than in the open nanohorns. Calculations of the isosteric heat of...

description We studied the adsorption of nitrogen on nanostructures of carbon with cylindrical (nanotubes) and conical (nanocones) geometries, when their ends are open or closed. It was found that the adsorption capacity of open nanotubes is more than in the open nanohorns. Calculations of the isosteric heat of adsorption were performed for both structures and it appears that, it is smaller for nanocones than for nanotubes in case that both are closed, on the entire range of pressures. For open structures at low pressure the isosteric heat of adsorption is greater for nanoconos than for nanotubes, and increasing the pressure, the opposite behaviour is observed.
