  The hydrogenation and deuteration of graphite with potassium intercalation
compounds (GICs) as starting materials was investigated. Characterization of
the reactions products (hydrogenated and deuterated graphene) was carried out
by thermogravimetric analysis coupled with mass spectrometry (TG-MS) and Raman
spectroscopy including statistical Raman spectroscopy (SRS) and -microscopy
(SRM). The results reveal that the choice of the hydrogen/deuterium source, the
nature of the graphite (used as starting material), the potassium concentration
in the intercalation compound as well as the choice of the solvent have a great
impact on the reaction outcome. Furthermore, it was possible to proof that both
mono and few-layer hydrogenated/deuterated graphene can be produced.
