Abstract The MnCO(3) with different structures was synthesized at room temperature or by hydrothermal method. The MnCO(3) phase obtained at room temperature could be transferred to Mn(2)O(3) plates by heat treatment at 600 degrees C. In contrast, porous Mn(2)O(3) nanostructures can be obtained after the heat treatment of MnCO(3) precursors prepared by hydrothermal method. Interestingly, Mn(2)O(3) phase can be also formed by heat treatment of the MnCO(3) phase obtained at room temperature(Mn-RT) at 120 degrees C. The products were characterized by means of XRD, SEM. The results clearly demonstrate a structure evolution from MnCO(3) precursors to Mn(2)O(3) structures on the completion of the reaction. The formation mechanism of the above materials was further investigated by TEM and FTIR. The capacitive properties of the Mn(2)O(3) materials were characterized by cyclic voltammetry. The results show that the morphologies and structures of Mn(2)O(3) samples play important roles on their capacitances.
