Graphene oxide exhibits interesting reactive events at its interface with water, with water as an active participant. The reactive events are influenced by the level of oxidation of the graphene oxide sheet. The fully oxidized sheet tends to make the interfacial water media acidic leaving the sheet negatively charged, whereas the reduced sheet can form comparatively long lived carbocations as well as split water forming two alcohol groups on the sheet.
氧化石墨烯在其与水的界面处表现出有趣的反应事件，水作为活性参与者。这些反应事件受氧化石墨烯片层氧化程度的影响。完全氧化的片层往往会使界面水介质呈酸性，使片层带负电荷，而还原的片层可以形成相对寿命较长的碳正离子，并分解水，在片层上形成两个醇基。
