“The reaction is convenient and cheap, and hydrogenated graphene may be applied within areas such as hydrogen storage. Additionally, upon functionalization of graphene one can open a bandgap and this fact is of high relevance for electronics applications,” says Prof. Henrik Ottosson.
Graphene reacts with formic acid in a water solution upon irradiation with visible light. In the reaction, formic acid acts as masked hydrogen and a material is produced where hydrogen extensively has been added to graphene. One says that graphene has been hydrogenated. Yet, graphene research is a side-project in Henrik Ottosson’s group...
