Abstract

Various manganese oxides nanoparticles can be synthesized using a versatile electrochemical method. In this method, KMnO4 solution was electrolyzed using carbon electrodes at 60 °C. By only adjusting the solution pH, the nanoparticles obtained can be α-MnO2 or Mn2O 3. In acid solution (pH ~4), the particles produced were α-MnO2. On the other hand, in basic solution (pH ~9), the particles produced were Mn2O3. Both α-MnO 2 and Mn2O3 particles are nearly spherical in shape with surface area ranging from 71-157 m2/g and diameter 1579-188 nm. The surface area and diameter are influenced by the voltage during electrolysis. The higher the voltage, the larger the diameter particles are.
