| Abstract: | In this paper, a-MnO was prepared throuth adjusting the reaction time, temperature and pH by liquid phase precipitation using potassium permanganate and manganese sulfate as raw materials. The sample was characterized by XRD and SEM. The results showed that the rod-like mMnO2 with sectional radius about 10-20 nm was prepered at 80- 90 ℃ and pH 1-2 in 4-6 hours. |
