摘要
Nitrogen adsorption on a model amorphous carbon surface is studied by means of computer simulation with the Monte Carlo method in the Canonical Ensemble. Both the surface model and the simulated adsorption isotherms have been compared with experimental results. The orientational configurations of nitrogen at different surface coverage at 77.5 K are studied. The cross-sectional area of the adsorbed molecules is determined and compared with values currently accepted in the literature. Surface density profiles of the adsorbed phase are also discussed.
