Hydrogenated graphene has been synthesized in one step by acetylene conversion in a helium plasma jet. A dc plasma torch with a diverging anode channel and a power up to 45 kW has been used to generate plasma. The obtained graphene materials have been studied by scanning electron microscopy, Raman spectroscopy, and elemental analysis. Hydrogen desorption from the samples synthesized has been studied by thermal analysis as a function of temperature. It has been found that during annealing in vacuum, the synthesis products change their morphology because of hydrogen release.
