N2 adsorption in an internal nanopore space of single-walled carbon nanohorn:: GCMC simulation and experiment

N-2 adsorption in the internal nanospace and on the external suface of the single SWNH particle is studied by grand canonical Monte Carlo simulation and is compared with the experimental result. The detailed comparison of the simulated adsorption isotherm with the experimental isotherm in the internal nanospaces provides 2.9 nm of the average pore width of the internal nanospaces.
