I need to synthesize Mn2O3 and Mn3O4 from MnO2 nanorods. What is suitable temperature to prepare Mn2O3 and Mn3O4 from MnO2 nanorods? Before, MnO2 nanorods were obtained by treating the amorphous MnO2 at 500◦C in air for 4h.
Nanostructured MnOx with crystalline phases of γ-MnOOH, δ-MnO2, α-Mn2O3, and Mn3O4 as well as rod, sheet, cube, and particle shapes were prepared via a facile, high-yield and low-temperature (60 °C) reduction route, without templates or surfactants
