A FeO/reduced graphene oxide (RGO)/FeO nanocomposite in situ grown on Fe foil was synthesized via a simple one-step hydrothermal growth process, where the iron foil served as support, reductant of graphene oxide, Fe source of FeO, and also the current collector of the electrode. When it directly acted as the electrode of a supercapacitor, as-synthesized FeO/RGO/FeO@Fe exhibited excellent electrochemical performance with a high capability of 337.5 mF/cm at 20 mA/cm and a superior cyclability with 2.3% capacity loss from the 600th to the 2000th cycle.
在 Fe 箔上原位生长的 FeO/还原氧化石墨烯（RGO）/FeO 纳米复合材料是通过简单的一步水热生长工艺合成的，其中 Fe 箔不仅作为支撑体、氧化石墨烯的还原剂、FeO 的 Fe 源，还作为电极的集流器。当它直接用作超级电容器的电极时，所合成的 FeO/RGO/FeO@Fe 表现出优异的电化学性能，在 20 mA/cm 的电流密度下具有 337.5 mF/cm 的高比电容，并且在第 600 次到第 2000 次循环中具有 2.3%的容量损失，具有出色的循环稳定性。
