▎ 摘　　要

We study the interplay of chemisorbed hydrogen and physisorbed PbPc molecules on epitaxial graphene by means of surface transport and density functional theory. While the adsorption of atomic hydrogen induces strong localization by local sp(3) rehybridization of the graphene lattice, PbPc is not affecting the transport properties of clean graphene. Moreover, on hydrogenated graphene, PbPc is selectively lifting the lattice distortion, while binding the atomic hydrogen and recovering the conductivity of the pristine graphene. Our results show that graphene is a multipurpose template for sensing both chemisorbed and physisorbed species and the implementation of a chemical selectivity.
