▎ 摘　　要

We focus on the description of a complex mechanism whereby the graphene electronic properties vary in the case of graphene hydrogenation as periodic graphene/graphane structures are formed. Two nonmonotonic dependences of the band gap on the hydrogen concentration and on the arrangement of adsorbed hydrogen atoms on the graphene surface were obtained. The origin of this effect is discussed and explained from an atomistic point of view. We discuss how one can possibly form the superlattice by using a graphene nanomesh.
