Vacancies in graphene attract hydrogen sulphide molecules. The result is sulphur chemisorption and hydrogen molecule release. Density functional theory computations indicate that graphene with vacancies is a metal, and becomes a semiconductor upon the adsorption of sulphur. It is found that vacancies induce a ferromagnetic state, in agreement with experimental observations.
