Effect of pulsed high-frequency discharge treatment of graphene oxide on low-temperature hydrogen sorption

By the scanning electron microscopy, X-ray diffraction and thermoprogrammed desorption the effect of treatment by pulsed high-frequency discharge in a hydrogen atmosphere on the morphology, structure, and sorption characteristics of thermally reduced graphene oxide (TRGO) was investigated. It is shown that treatment with a pulsed gas discharge increased the physical sorption of hydrogen by a factor of 1.5. It can be assumed that the increase in the sorption capacity is due to in the distance between adjacent carbon surfaces in packages of graphene planes during their chemical interaction with ionized during the discharge process hydrogen.
