  In this work we present a fully atomistic reactive (ReaxFF force field)
molecular dynamics study of the structural and dynamical aspects of the
one-side hydrogenation of graphene membranes, leading to the formation of the
so-called graphone structure. We have considered different substrates:
graphene, few-layers graphene, graphite and platinum at different temperatures.
Our results showed that the hydrogenation rates are very dependent on the
substrate and thermal effects. Our results also showed that, similarly to
graphane, large hydrogenated domains are unlikely to be formed. These
hydrogenation processes occur through the formation of uncorrelated cluster
domains.
