20.500.12556/DiRROS-31014 Reduction of graphene oxide flakes by treatment with non-equilibrium hydrogen plasma–review and challenges Graphene oxide (GO) is a standard precursor for the synthesis of porous yet densely packed, graphene-like structures in films with a thickness of several micrometers, which are useful for electrodes in various electrochemical devices, such as supercapacitors, as well as for various sensors. As-synthesized GO films exhibit inadequate electrical conductivity because of a large concentration of oxygen chemically bonded to graphene sheets. Heating of GO films in a non-oxidizing atmosphere will cause thermal decomposition of GO by desorption of carbon oxides, which will result in numerous defects in the sheets and partial collapsing of the sheets. An alternative is the treatment of GO films with non-equilibrium hydrogen plasma, which causes reduction rather than decomposition of the GO sheets. The scientific literature on approaches to reducing GO samples by treatment with hydrogen plasma is reviewed, the results are critically evaluated, and the correlations between the reduction efficiency and processing parameters are drawn. Paradoxically, larger discharge powers lead to worse results, both in terms of the remaining oxygen concentration and electrical properties. A feasible explanation for this paradox is radiation damage, which is likely caused by energetic photons or ions. The recommendation for further experiments in this tremendously promising niche is also presented. graphene oxide hydrogen plasma carbon materials grafenov oksid vodikova plazma ogljikovi materiali true false true Springer Nature Angleški jezik Slovenski jezik © The Author(s) 2026 Neznano 2026-07-10 08:55:42 2026-07-10 08:55:43 2026-07-11 03:51:11 0000-00-00 00:00:00 2026 0 0 Nasl. z nasl. zaslona; Soavtorji iz Slovenije: Rok Zaplotnik, Alenka Vesel, Gregor Primc, Miran Mozetič; Opis vira z dne 9. 7. 2026; str. 1-28 Vol. 10, article no. 13 Jun. 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2026-01-26 2026-06-14 2026-06-26 621.7+621.9 2367-3192 10.1007/s41614-026-00223-z 284223747 https://link.springer.com/article/10.1007/s41614-026-00223-z 1 606d4a29-7c2c-11f1-b663-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=47756 RAZ_Zelenak_Frantisek_2026.pdf RAZ_Zelenak_Frantisek_2026.pdf 1 59A4C9663E5614B134CE7609CE0B1B04 9ecde7c9253f9b3295894a17d86eca38a8a9b44dc7672b0dc3050bee86774385 1bf1f66b-7c2d-11f1-b663-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=47760 Institut Jožef Stefan 0 0 0
