Abstract
Beta-Manganese dioxides' (β-MnO2) hollow octahedra have been prepared by a synergetic redox reaction using cuprous chloride (CuCl) and hydrochloric acid (HCl) as reductants and potassium permanganate (KMnO4) as oxidant through a hydrothermal route. During the process, the self-generated chlorine (Cl2) gas bubbles and HCl's etching appear to be necessary for the formation of MnO2 hollow structure. The catalytic efficiency of the prepared β-MnO2 hollow octahedra was high which has been demonstrated by the catalytic oxidation of methylene blue (MB) dye in the presence of hydrogen peroxide (H2O2) under natural light.
