Local curvature in graphene can enhance its reactivity and catalytic activity be induced by the adsorption of certain chemical species. By employing periodic density functional theory (DFT) calculations, we demonstrate that significant local systematically observed when lanthanide atoms (the full series from La to Lu) are adsorbed on Stone-Wales (SW) defect graphene, contrary defect-free graphene. Despite typical high coordination numbers species, their hapticity is always η
