Inspired by an ancient reducing method used in textile production, sodium hydrosulfite was used to reduce graphite oxide as an efficient reducing agent in our work. The reduced materials were characterized by x-ray photoelectron spectroscopy, thermogravimetric analysis, wide-angle x-ray scattering, Raman spectroscopy, solid state (13)C NMR spectroscopy and electrical conductivity measurements, respectively. The results showed that graphite oxide can be reduced with sodium hydrosulfite in a few minutes, with a degree of reduction comparable to those achieved with hydrazine. It provides an efficient method to reduce graphite oxide and could be used as a method to prepare novel composites.
受纺织生产中一种古老还原方法的启发，本工作使用连二亚硫酸钠作为高效还原剂还原氧化石墨。通过 X 射线光电子能谱、热重分析、广角 X 射线散射、拉曼光谱、固态（13）C NMR 光谱和电导率测量分别对还原材料进行了表征。结果表明，氧化石墨可以在几分钟内被连二亚硫酸钠还原，还原程度与水合肼相当。该方法为还原氧化石墨提供了一种有效方法，并可用于制备新型复合材料。
