摘要:
Transition metal oxide nanostructures are current research focus for energy storage applications. We herein report the synthesis of MnO2-NiO nanoflake-assembled tubular array on stainless steel substrate to function as pseudocapacitor electrode by programmed three-dimensional (3D) interfacial reactions, in which the ZnO nanowire array is employed as the low-cost in situ sacrificial template. In this 3D nanoelectrode, MnO2 and NiO nanoflakes share the same "root" and form an integrated hierarchical structure, which adheres robustly to the substrate. Importantly, both MnO 2 and NiO contribute to...
