一般描述
氧化石墨烯的结构类似于含有残余氧、杂原子和结构缺陷的石墨烯。还原氧化石墨烯 (rGO) 可以从氧化石墨 (GO) 浆料的水溶液中以薄膜形式提取。许多现代合成 GO 的方法都是基于 Hummers 法，即石墨被高锰酸钾硫酸溶液氧化。曾报告使用肼还原 GO。然而，肼是剧毒的并且能潜在地与氮杂原子起作用去。由于这些问题，包括 NaBH 4 、抗坏血酸和 HI 等肼的替代品已被用于还原 GO。GO 可以作为薄膜或在水溶液中还原。最近对还原方法进行了审查。
应用
利用旋涂还原氧化石墨烯 (rGO) 薄膜作为缓冲层制备体异质结有机太阳能电池。聚乙二醇化 rGO 可用于：
- 化学传感器、生物传感器
- 作为发光二极管 (LED) 和 ITO 中的透明电极
- 锂离子电池。
