On thermodynamics & experimental evidences of the Kurdjumov and spillover effects in carbon nanostructures, under self-intercalation of high density hydrogen

Experimental evidences and thermodynamics of the self-intercalation of high-density gaseous molecular hydrogen (ρH2 ≈ 0.045 g/cm3, at 300 K) into surface nanoclusters in highly oriented pyrolytic graphite and epitaxial graphene, as well as the self-intercalation of high density solid molecular hydrogen (ρH2 ≈ 0.5 g/cm3, at 300 K) into graphite nanofibers are considered, with regard to the problem of compact and efficient hydrogen on-board storage. The manifestation and physics of the Kurdjumov and spillover effects in carbon nanostructures, under self-intercalation of high density hydrogen, are discussed. Perspectives of a further development of these results are considered, as well. This work was financially supported by the RFBR (Project # 18-29-19149 mk).
