. ▁Graph ane ▁should ▁not ▁be ▁confused ▁with ▁graph ene , ▁a ▁two - dimensional ▁form ▁of ▁carbon ▁alone . ▁Graph ane ▁is ▁a ▁form ▁of ▁hydro gen ated ▁graph ene . ▁ ▁Graph ane ' s ▁carbon ▁b onds ▁are ▁in ▁sp 3 ▁configuration , ▁as ▁opposed ▁to ▁graph ene ' s ▁sp 2 ▁bond ▁configuration , ▁thus ▁graph ane ▁is ▁a ▁two - dimensional ▁analog ▁of ▁cub ic ▁diam ond . ▁ ▁Str ucture ▁The ▁structure ▁was ▁found , ▁using ▁a ▁cluster ▁expansion ▁method , ▁as ▁the ▁most ▁stable ▁of ▁all ▁the ▁possible ▁hydro gen ation ▁r ati os ▁of ▁graph ene ▁in ▁ 2 0 0 3 . ▁In ▁ 2 0 0 7 , ▁research ers ▁found ▁that ▁the ▁comp ound ▁is ▁more ▁stable ▁than ▁other ▁comp ounds ▁containing ▁carbon ▁and ▁hydro gen , ▁such ▁as ▁ben z ene , ▁cy clo hex ane ▁and ▁poly eth yl ene . ▁This ▁group ▁named ▁the ▁predicted ▁comp ound ▁graph ane , ▁because ▁it ▁is ▁the ▁fully ▁s atur ated ▁version ▁of ▁graph ene . ▁The ▁comp ound ▁is ▁an ▁ins ulator . ▁Chem ical ▁functional ization ▁of ▁graph ene ▁with ▁hydro gen ▁may ▁be ▁a ▁suitable ▁method ▁to ▁open ▁a ▁band ▁gap ▁in ▁graph ene . ▁ ▁P - d oped ▁graph ane ▁is ▁proposed ▁to ▁be ▁a ▁high - temper ature ▁B CS ▁theory ▁super con duct or ▁with ▁a ▁T c ▁above ▁ 9 0 ▁K . ▁ ▁Any ▁dis order ▁in ▁hydro gen ation ▁con formation ▁tends
