Clear and uniform one-dimensional (1D) α-MnO2 nanorods with diameters of 30–50 nm were prepared by hydrothermal treatment of homogeneous solution of hydrated MnSO4 and KMnO4 with a little H2O2. Upon control of hydrothermal conditions (reaction temperature and duration time), an excellent crystalline phase of MnO2 was obtained and its morphology was investigated. The crystal structures of as-synthesized MnO2 products have been characterized by x-ray diffraction (XRD). The morphology of the product was examined by scanning electron microscopy (SEM) and the chemical composition was analyzed using energy dispersive spectroscopy (EDS) along with SEM. The Mn concentration was determined by the chemical titration method
