水合肼还原氧化石墨烯的研究

Research on the Reduction of Graphene Oxide with Hydrazine Hydrate

通过改进的Hummers法制备氧化石墨,将获得的氧化石墨进行热剥离以及超声剥离得到双层甚至单层的氧化石墨烯片。然后采用化学还原--水合肼还原的方法去除氧化石墨烯所含的羧基COOH、羟基OH、羰基C=O和环氧基等化学基团。本实验着重研究了还原剂的用量和反应时间对各个化学基团的影响规律。

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 carboxyl COOH,hydroxyl OH,Carbonyl C = 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 investigated.
