We use density functional theory ΝDFTΝ with a recently developed van der Waals density functional ΝvdW-DFΝ to study the adsorption of graphene on Co, Ni, Pd, Ag, Au, Cu, Pt, and AlΝ111Ν surfaces. In contrast to the local-density approximation ΝLDAΝ which predicts relatively strong binding for Ni,Co,
