Co3O4 Nanowire@MnO2 Ultrathin Nanosheet Core/Shell Arrays: A New Class of High-Performance Pseudocapacitive Materials

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 rangi...

Summary: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.
