Supercapacitors are electrochemical energy storage devices potentially useful for high power demanding applications. Three-dimensional nanostructures of metal oxides and conducting polymers are considered as promising candidates for the development of high-performance supercpacitor electrodes. Here, we will discuss about the preparation of different kinds of nanoarrays such as nanotube arrays and core-shell nanowire arrays, by using anodic alumina nano-templates. Alumina templates can be employed to make well ordered three-dimensional nanostructures with superior surface properties. Our strategies mainly include the preparation of MnO2 and PEDOT nanotube arrays, Ni-NiCo2O4 core-shell nanowire arrays and NiCo2O4-TiO2-NiCo2O4 sandwich-structured nanotube arrays, and the fabrication of supercapacitors by utilizing these nanoarrays shall be useful for wide range of applications.
