Sb2O3 nanoparticles are uniformly anchored on reduced graphene oxide (rGO) sheets via a facile and ecofriendly route based on the alcohol dissolution–reprecipitation method. Such obtained Sb2O3/rGO composite demonstrates a highly reversible specific capacity (1355 mA h g–1 at 100 mA g–1), good rate capability, and superior life cycle (525 mA h g–1 after 700 cycles at 600 mA g–1) when used an anode electrode for lithium-ion batteries (LIBs). The outstanding electrochemical properties of Sb2O3/rGO composite could be attributed to its unique structure in which the strong electronic coupling effect between Sb2O3 and rGO leads to an enhanced electronic conductivity, structure stability, and electrochemical activity during reversible conversion-alloying reactions. Also, these findings are helpful in both developing novel high-performance electrodes for LIBs and synthesizing functional materials in an ecofriendly and economical way.

通过醇溶-再沉淀法将Sb 2 O 3纳米颗粒固定在石墨烯片上，从而具有优异的储锂性能
Sb 2 O 3纳米颗粒通过一种基于醇溶-再沉淀法的简便而环保的方法均匀地锚固在还原的氧化石墨烯（rGO）板上。这样获得的Sb 2 ö 3 / RGO复合演示了一个高度可逆比容量（1355毫安汞柱-1在100mA克-1），良好的倍率性能和优异的寿命周期（525毫安汞柱-1后以600mA克700次循环–1）当用于锂离子电池（LIB）的阳极时。Sb 2 O 3的出色电化学性能/ rGO复合材料可归因于其独特的结构，其中Sb 2 O 3和rGO之间的强电子耦合效应导致可逆转化合金化反应过程中增强的电子电导率，结构稳定性和电化学活性。同样，这些发现对于开发新型的LIB高性能电极以及以环保和经济的方式合成功能材料都很有帮助。
