摘要：
A smart hybrid nanowire array consisting of Co3O4 porous nanowire core and a MnO2 ultrathin nanosheet shell is fabricated using a general 3D interfacial carbon-assisted hydrothermal method. The array exhibits a high capacitance with good cycle performance and remarkable rate capability that is ranging among the best reported to date for hybrid metal oxide systems in the absence of a conducting matrix.
