The Synthesis of Α-Mno2nanorods Using Hydrothermal Homogeneous Precipitation

AbstractClear and uniform one-dimensional (1D) α-MnO2nanorods with diameters of 30–50 nm were prepared by hydrothermal treatment of homogeneous solution of hydratedMnSO4andKMnO4with a littleH2O2. Upon control of hydrothermal conditions (reaction temperature and duration time), an excellent crystalline phase ofMnO2was obtained and its morphology was investigated. The crystal structures of as-synthesizedMnO2products 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.
