Description
Summary:Nest-like hollow structure of MnO sub(2) was synthesized via a simple and facile hydrothermal procedure without using any template or surfactant. The morphology of MnO sub(2) nanostructures can be easily controlled by altering the reaction time. The architectural feature of hollow nest-like MnO sub(2) was investigated by using field emission scanning electron microscopy, transmission electron microscopy, and high-resolution transmission electron microscopy. This nest-like hollow nanosphere of MnO sub(2) exhibits prominent electrochemical properties, such as the considerable specific capacitance of 211.1 F g super(-1) at 1 A g super(-1), excellent voltammograms property and the remarkable long-term cycling stability with 93.6 % surplus of capacitance after 1000 cycles. From the above, this nest-like hollow nanostructured MnO sub(2) is a promising electrode material for supercapacitor.
