In this work, MnO2 nanostructure powders with different crystalline phases have been successfully prepared by hydrothermal and sol-gel methods. The obtained products were characterized by XRD and SEM techniques and their crystallographic phases and morphological properties compared. Results showed that alpha-MnO2, beta-MnO2, and delta-MnO2 nanorods were synthesized by hydrothermal method and gamma-MnO2 polymorph was obtained by sol-gel method.
