DETAILED DESCRIPTION - Obtaining and splitting poly-layer graphane (polygraphane) comprises loosely connecting graphane layers comprising, as most of known methods for producing graphane (monographane) of graphene (monographene), using carbon material source loosely coupled graphene layers (printing), which differs from known methods for producing graphane from graphene, lacking of a new way of step (operation) of obtaining a monolayer graphene, and giving a multilayer graphene, and not in monolayer form with no monolayer graphene hydrogenation, and fragments of original multilayer graphene (printing) contained in carbon structures (in graphite nano-fibers), splitting (division) of fragments of polygraphane megabar highly compact hydrogen (i.e. hydrogen corresponding to a pressure of about 1 Mbar), formed in material due to association energy of atomic hydrogen, which is carried out through a set of following sequence: used as most economical feedstock produced from different companies (with use of different methods of synthesis) of certified carbon materials consisting fragments of multilayer graphene, a fragmented polygraph (graphite nano-fibers (nano-fibers), carbon nano-tubes (nano-tubes), carbon nano-cells (nano-shells), or carbon fibers (fibrils)), and conducting pre-treatment of material, for example by annealing material in an inert gas from impurities and associated functional groups of oxide, and others like that prevent or hinder hydrogen sorption materials; provide any sufficiently technologically advanced and cost-effective way, for example by hydrogenation of material in gaseous molecular hydrogen at technological pressures (pH2 (gas)), hydrogenation temperature and time, not exceeding 300 bars (30 MPa), 1000 K and 300 hours, respectively, formation of border (near surface) of defective areas (layers) multilayer graphene fragments of material (fragmented printing) carbohydride layer chemisorbed hydrogen desorption activation energy of about 1.2 eV, and well as education on inner (graphene) surfaces in multilayer graphene fragments of material (fragmented printing) layer chemisorbed hydrogen desorption activation energy of about 2.5 eV, producing of graphane-like multilayer regions (fragmented polygraphane) in predominant part of fragments of material; controlled hydrogenation process material through periodic, temperature-programmed desorption (TPD) of hydrogen for hydrogenation of material provided by any technologically advanced and cost-effective way, for example by catalytic atomization of molecular hydrogen formation in between fragment areas and/or near-surface layers of fragments of material (fragmented printing industry and/or polygraphane) of atomic hydrogen with a local (partial) pressure Ph (gas) of 10-100 Pa at which intercalation highly compact megabar of hydrogen (in amount of order of 10 or more wt.%) between graphene and/or layers in graphyne excerpt providing splitting (division) of multilayer graphyne fragments material control process of intercalation highly compact megabar hydrogen between graphene (and/or graphyne) layers in fragments of material and multilayer graphyne cleavage fragments material by TPD of hydrogen, gravity and electron microscopic studies of material, with use of catalytic hydrogen in atomization of between fragment defective material (fragmented graphene) previously administered by any conventional means, such as chemical or electrochemical, a certain amount of metal nano-particles catalyst (at least one from group of metals, dissociatively absorbing hydrogen, and containing palladium (Pd), platinum (Pt), nickel (Ni), titanium (Ti), iron (Fe), cobalt (Co), niobium (Nb), molybdenum (Mo), tantalum (Ta), tungsten (W), rhodium (Rh), ruthenium (Ru), osmium (Os), iridium (Ir), lanthanum (La), magnesium (Mg), and/or their alloys) are necessary and sufficient for local atomization of molecular hydrogen and ensure adequate partial pressure of atomic hydrogen (pH (gas)) of 10-100 Pa of between fragment areas and/or near-surface layers of fragments of material are removed from material highly compact megabar hydrogen intercalated between graphene and/or graphyne layers in fragments of material, by a sharp decrease (by tens of percent or more) of hydrogen pressure and subsequent low-temperature annealing of material, material is removed from chemisorbed hydrogen corresponding TPD peak with an activation energy of bout 1.2 eV, by thermo-desorption annealing, in which material is only chemisorbed hydrogen corresponding TPD peak with an activation energy of about 2.5 eV, only saved multilayer graphene fragments, split into separate slotted nano-cavities nano-regions, and last operation can be combined with previous operation.
