Abstract: α-MnO2 and β-MnO2 nanorods were prepared directly by facile hydrothermal process at 150 ℃ and 220 ℃, respectively. The as-prepared α-MnO2 and β-MnO2 nanorods were shown to be phase-pure single crystallites as evidenced by XRD, TEM and SEM results. Further experiments show that the as-prepared α-MnO2 and β-MnO2 nanorods have catalytic effect on the oxidation and decomposition of the methylene blue(MB) dye with H2O2. The catalytic activity of β-MnO2 is much higher than that of α-MnO2.
