graphane

Germanane's structure is similar to graphane, itself related to graphene.

Graphane is a great example of this.

After taking up hydrogen, the substance becomes graphane.

Graphane should not be confused with graphene, a two-dimensional form of carbon alone.

Graphane is a form of hydrogenated graphene.

The first theoretical description of graphane was reported in 2003 and its preparation was reported in 2009.

Graphane is a two-dimensional polymer of carbon and hydrogen with the formula unit (CH) where n is large.

Full hydrogenation from both sides of a graphene sheet results in graphane, but partial hydrogenation leads to hydrogenated graphene.

Because the latter are distributed randomly, obtained graphane is expected to be disordered material in contrast to two-sided graphane.

If graphene rests on a silica surface, hydrogenation on only one side of graphene preserves the hexagonal symmetry in graphane.

Graphane's carbon bonds are in sp configuration, as opposed to graphene's sp bond configuration, thus graphane is a two-dimensional analog of cubic diamond.

In addition to three known derivatives of graphene: grapheneoxide GO, graphane CH and fluorographene CF, the successful synthesis of chlorinated graphene (chlorographene) was also achieved very recently.

Scientists have asserted that the carbon spherules originated as fungal structures and/or insect fecal pellets, and that the claimed nanodiamonds are actually misidentified graphene and graphene/graphane oxide aggregates.
