Comparative Study of Hydrogen Adsorption in Slit-like Pores of Carbon Adsorbents and on Fullerene Molecules

Abstract

Adsorption of hydrogen in slit-like pores of carbon adsorbents and on fullerene molecules was investigated using the classical density functional theory. Hydrogen adsorption in a gap between two graphene walls was calculated at different temperatures and pressures. The obtained results agree with the data found using the Dubinin theory of the volume pore filling and with the available molecular dynamics results. It has been shown that conventional carbon adsorbents corresponding to the slit-like model and fullerene materials should have approximately equal storage capacities. However, such a capacity is sufficient for practical storage and use of hydrogen at low temperatures only (at about 20 K), and at room temperatures some special active sites of adsorption should be used to solve the problem under consideration.
