Abstract: High purity α-MnO 2 rectangular nanowires are synthesized by a facile one-step hydrothermal method. The morphology and composition of α-MnO 2 nanowires are characterized by X-ray diffraction, energy-dispersive X-ray spectroscopy (EDX), Field emission scanning electron microscopy (FESEM), X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared (FTIR) spectral techniques. The electrochemical properties of α-MnO 2 nanowires have been studied as electrode material for supercapacitors. The α-MnO 2 nanowires exhibit a high specific capacitance of 362 Fg -1 at a current density of 1.0 Ag -1 with a good cycling stability (maintained 83% after 5000 cycles). These results indicate its promising applications as a high-performance electrode material for electrochemical energy storage.
