A nanocomposite for the reverse storage of hydrogen based on monolayer sheets of polycrystalline or monocrystalline grapheme having a form of a cylindrical spiral roll of polycrystalline or monocrystalline graphene with a preferably constant spacing in the range from 0.2 to 2 nm, whereby the said spiral roll of polycrystalline graphene has grains with a minimum diameter of 50 nm.

Nanocomposite based on graphene for reversible storage of hydrogen

A method for producing a graphene layer on a multilayered plate containing, as the graphene forming matrix, an external layer composed of a metal or a metal alloy and, as a support substrate, the transition metals and/or their alloys and/or metalloids and/or their solutions and compounds, the method involving subjecting the multilayered plate to heat treatment in the following stages: plate heating until the plate reaches a temperature that is between 0.5&#xb0; C. and 50&#xb0; C., annealing, at a constant or variable temperature from the temperature range, for a period between 60 and 600 seconds and cooling, with the cooling rate maintained between 0.1 and 2&#xb0; C./min in the temperature range of 1,200&#xb0; C.-1,050&#xb0; C.
