The absorption of different small gas molecules on graphene is investigated based on the pseudopotential method within the density functional theory formalism. The preferred adsorption site (among the top, bridge, and hollow positions) and orientations of these molecules on the graphene surface are analyzed and the related adsorption energies are calculated. The charge transfer between the absorpted molecules and the graphene is discussed as well.
