| Summary: | A series of MnO2 nanoparticles were synthesized by two-step reaction in the ethanol-water system with urea as reducing agent. During the novel routine, P123 polymer plays a crucial role in controlling the morphology. Then, characterization and systematic investigations of the samples by transmission electron microscopy and scanning electron microscopy confirmed that the morphology of MnO2 nanoparticles changed as the raw materials ratio changed. Finally, X-ray diffraction and X-ray photoelectron spectroscopy were employed to confirm the crystal structure and the exact components. These results indicated the particles showed a rod-like shape without P123 and changed into sheet-like shape after the addition of P123. Therefore, this idea could be developed for the controllable synthesis of other metal oxide-based nanomaterials. |
