以二甲基亚砜（DMSO）和水为溶剂和反应物，采用一步法原位合成SnO 2/石墨烯（SG）纳米复合材料。氧化石墨烯（GO）的还原和SnO 2纳米粒子的原位形成在一个步骤中实现。电化学实验表明，复合材料具有较好的储锂性能。本文提出的方法为制备金属/石墨烯纳米复合材料提供了一种有效、经济、绿色的策略。
A facile one-step solution-based process to in situ synthesize SnO2/graphene (SG) nanocomposites was developed, by using the mixture of dimethyl sulfoxide (DMSO) and H2O as both solvent and reactant. The reduction of graphene oxide (GO) and the in situ formation of SnO2 nanoparticles were realized in one step. The electrochemical experiments showed the composites provided a better Li-storage performance. The method presented in this paper may provide an effective, economic, and green strategy for the preparation of metal-codde/graphene nanocomposites.
