| Popis: | The process of thermal decomposition of MnO2 nanorods was reported in this paper. The MnO2 nanorods were synthesized via hydrothermal method. The process of their thermal decomposition was studied by thermogravimetry-differential scanning calorimetry (TG-DSC). For the further analysis of the product during thermal decomposition, the MnO2 nanorods were calcined at 700 and 1000°C in the muffle furnace, respectively. The products were characterized by X-ray diffraction (XRD) and X-ray photoelectron spectra(XPS). The results showed that MnO2 nanorods were only decomposed at about 800°C, and the characteristic peaks of Mn2O3 cannot be found in either XRD or XPS. There were only the characteristic peaks of Mn3O4. Moreover, the changes of morphology were observed by field emission scanning electron microscopy (FE-SEM). Furthermore, the process analysis of this phenomenon was speculated. |
