Abstract

One-dimensional manganese oxide nanobelt bundles with layered structure have been synthesized by hydrothermally treating the precursor, K-type layered manganese oxide in a NaOH solution of 6.0 mol L−1 at 150 °C for 30 h. The obtained material is characterized by XRD, SEM, TEM and BET analysis. The manganese oxide nanobelt bundles are more than 50 μm long and 20–50 nm wide, and the specific surface area is about 160 m2 g−1. The electrochemical property of the synthesized manganese oxide nanobelt bundles has been studied using cyclic voltammetry in a mild aqueous electrolyte. The manganese oxide nanobelt bundle exhibits good capacitive behavior and cycling stability in a neutral electrolyte system, and its initial capacitance value is 268 F g−1.
