Methane Adsorption on Aggregates of Fullerenes: Site‐Selective Storage Capacities and Adsorption Energies [PDF]

open access: yesChemSusChem, 2013
AbstractMethane adsorption on positively charged aggregates of C60 is investigated by both mass spectrometry and computer simulations. Calculated adsorption energies of 118–281 meV are in the optimal range for high‐density storage of natural gas. Groove sites, dimple sites, and the first complete adsorption shells are identified experimentally and ...
