The above article proves by means of a cluster expansion that the alternating below and above graphene sheet hydrogenation is the lowest energy configuration. However, the graphane structure was not given its name at the time - the name "graphane" derives from the 2007 article by Sofo et al (ref. 1), but the structure, and its identification as the most stable hydrogenated form of graphene was already found in 2003. The 2003 article mentioned above preceedes all the other literature in the article, maybe it could be mentioned in the article?

My notice to the subject: Now they usually imply that the term graphane is used for a case when all graphene's bonds are saturated with hydrogen atoms. All other configurations with partly covered surface of graphene usually named as "graphane-like" structures. Graphane and graphane-like structures can be formed by electrolytic hydrogenation of graphene or few layer graphene or high oriented pyrolytic graphite. In the last case mechanical exfoliation of hydrogenated top layers can be used. Please, see the paper A.M.Ilyin et al. "Computer simulation and experimental study of graphane-like structures formed by electrolytic hydrogenation" Physica E, 43 (2011) 1262-1265, doi: 10.1016/j.physe.2011.02.012. with best regards Arkady Ilyin — Preceding unsigned comment added by 178.88.203.25 (talk) 10:25, 18 July 2012 (UTC)

Real or conjectured?

Is it my impression, or is this material only a conjecture at the current time? If so, it should be stated in the lead.--Jorge Stolfi (talk) 23:14, 2 January 2011 (UTC)

Well, the article and ref. 3 suggest it was produced (I haven't read that Science article though to say how certain it was). Materialscientist (talk) 23:38, 2 January 2011 (UTC)

Same or different

The current text states two contradtictory things:

1. "Graphane is hydrogenated graphene."
2. "Full hydrogenation from both sides of graphene sheet results in graphane, but partial hydrogenation leads to hydrogenated graphene."

The first states they are the same, the second that they are different.

It appears obvious from the description that they are different but related. Am changing the first statement to say "Graphane is a form of hydrogenated graphene." If you can think of a better way of putting it, then go ahead. Nanobug (talk) 20:18, 16 April 2011 (UTC)
