摘要:
A smart hybrid nanowire array consisting of Co<inf>3</inf>O<inf>4</inf> porous nanowire core and a MnO<inf>2</inf> 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. &copy;2011 WILEY-VCH Verlag GmbH &amp;Co. KGaA, Weinheim.
