Synthesis of Mn3O4 octahedrons and other manganese-based nanostructures through a simple and green route

Abstract
Several manganese-based nanostructures, including novel Mn3O4 octahedrons, MnOOH nanorods, MnO2 nanowires and aggregated MnCO3 nanoparticles in the form of spindles, have been prepared through the redox reactions between KMnO4 and sodium carboxymethyl cellulose.
