Adsorption of para-Hydrogen on Fullerenes

Statistical Mechanics 2009-11-10 v2

Abstract

Adsorption of para-Hydrogen on the outer surface of a single fullerene is studied theoretically, by means of ground state Quantum Monte Carlo simulations. We compute energetics and radial density profiles of para-Hydrogen for various coverages on a variety of small fullerenes. The equilibrium adsorbed monolayer is commensurate with the surface of the fullerene; as the chemical potential is increased, a discontinuous change is generally observed, to an incommensurate, compressible layer. Quantum exchanges of Hydrogen molecules are absent in these systems.
