... MnO 2 films composed of nanoflakes have been reported to be easily produced in a hydrothermal reaction of KMnO 4 solution without CNTs [24, 25]. The formation of MnO 2 in such hydrothermal reaction ... nanostructure of the MnO 2 layer. A highly porous MnO 2 layer composed of interconnected nanoflakes is introduced in the present study instead of a dense MnO 2 layer co...
