首先通过室温下MnO2纳米片与吸附的Fe2+离子之间的原位氧化还原反应开发了一种设计和可控制备多孔MnO2纳米片的新技术，其中Fe2+离子源自Cu线和Fe3+离子之间的氧化还原反应。当MnO2纳米片用作超级电容器电极时，面内纳米孔的形成明显提高了倍率性能。
A novel technique for the design and controllable preparation of holey MnO2 nanosheets was first developed by an in situ redox reaction between the MnO2 nanosheets and adsorbed Fe2+ ions at room temperature, in which Fe2+ ions originated from a redox reaction between Cu wire and Fe3+ ions. The formation of in-plane nanopores on the MnO2 nanosheets obviously improved the rate capability when they were used as promising supercapacitor electrodes.
