We have performed an experimental investigation on the effects of hydrazine treatment on graphene oxide via a reaction-model approach. Hydrazine was reacted with small conjugated aromatic compounds containing various oxygen functional groups to mimic the structure of graphene oxide. The hydroxyl and carboxylic groups were not readily removed while carbonyl groups reacted with hydrazine to form the corresponding hydrazone complexes. In the presence of adjacent hydroxyl groups, carboxyl groups underwent thermal decarboxylation.
我们通过反应模型方法对肼处理氧化石墨烯的效果进行了实验研究。肼与含有各种氧官能团的小共轭芳香化合物反应，以模拟氧化石墨烯的结构。羟基和羧基不易去除，而羰基与肼反应形成相应的腙配合物。在相邻羟基存在的情况下，羧基发生热脱羧反应。
