受古代纺织生产中还原法的启发，采用保险粉作为还原剂对氧化石墨进行还原。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光谱和电导率测量对还原后的材料进行了表征。结果表明，氧化石墨可以在几分钟内被连二亚硫酸钠还原，还原程度与肼相当。这为氧化石墨的还原提供了一种有效的方法，并可作为制备新型复合材料的一种方法。
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 13C 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.
