Hydrogen and deuterium atoms interact with a graphene monolayer on a Ni/Au substrate. The atoms are either adsorbed on the surface, or reflected, or they can force a previously chemisorbed atom to leave graphene in the form of a gas molecule. The kinetic isotope effect is investigated by time-dependent X-ray photoelectron spectroscopy.
