title: Rational design and controllable preparation of holey MnO2nanosheets.
abstract: A novel technique for the design and controllable preparation of holey MnO2nanosheets was first developed by an in situ redox reaction between the MnO2nanosheets 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 MnO2nanosheets obviously improved the rate capability when they were used as promising supercapacitor electrodes.
