Abstract
Bi-component Mn3O4–MnO2 nanorods with lengths of up to 30μm are synthesized using a simple hydrothermal method in the absence of templates. Samples were characterized by FE-SEM, HR-TEM, XRD, XPS, and N2 adsorption–desorption. The results indicate that the Mn3O4–MnO2 and Mn5O8 samples with various morphologies can be easily obtained via modulating Cl− ions and glucose contents. Compared with that of the Mn5O8 samples, the bi-component Mn3O4–MnO2 nanorods exhibited higher catalytic properties for oxidative decomposition of MB owing to its adjustable valence state and oxygen content.
