Research on the Reduction of Graphene Oxide with Hydrazine Hydrate

Graphite oxide was prepared by improved Hummers method.Through the hot peeling and supersonic peeling of the obtained graphite oxide,we can obtain double-decked,even single-layer graphene oxide piece.was obtained.Then the chemistry groups such as carboxylCOOH,hydroxylOH,CarbonylC = O and epoxy group were removed through chemical reduction——hydrazine hydrate reduction method.effect of reducing agent amount and reaction time on each chemistry function groups was in vestigated.
