Embodiment 1
[0019] 0.5 mmol of potassium permanganate and 2 mmol of manganese chloride were dissolved in 25 ml of deionized water, and 0.1 g of polyvinylpyrrolidone and 0.5 ml of 30% hydrogen peroxide were added. After 1.25 mmol of lithium carbonate was added to the above solution, the mixture was transferred to a high-pressure reactor lined with polytetrafluoroethylene, the reactor capacity was 30 ml, and the temperature was kept at 180° C. for 18 hours. After cooling, filter, wash with deionized water and absolute ethanol, and dry the product. Depend on figure 2 The XRD pattern of the product shows that the sample is manganese carbonate with high purity. image 3 , 4 It shows that the diameter of manganese carbonate nanorods is 50-100nm, the length is 1-2μm, and the obtained manganese carbonate nanorods are single crystals.
Embodiment 2
[0021] 0.5 mmol of potassium permanganate and 2 mmol of manganese chloride were dissolved in 25 ml of deionized water, and 0.1 g of polyethylene glycol-6000 and 0.5 ml of 30% hydrogen peroxide were added. After adding 1.25 mmol of lithium carbonate to the above solution, the mixture was transferred into a high-pressure reactor lined with polytetrafluoroethylene, the reactor capacity was 30 ml, and the temperature was kept at 180° C. for 18 hours. After cooling, filter, wash with deionized water and absolute ethanol respectively, and dry the product to obtain manganese carbonate nanorods with a diameter of 50-100 nm and a length of 1-2 μm, and the manganese carbonate nanorods are single crystals.
Embodiment 3
[0023] 0.5 mmol of potassium permanganate and 2 mmol of manganese chloride were dissolved in 25 ml of deionized water, and 0.1 g of cetyltrimethylammonium bromide and 0.5 ml of 30% hydrogen peroxide were added. After adding 1.25 mmol of lithium carbonate to the above solution, the mixture was transferred into a high-pressure reactor lined with polytetrafluoroethylene, the reactor capacity was 30 ml, and the temperature was kept at 180° C. for 18 hours. After cooling, filter, wash with deionized water and absolute ethanol respectively, and dry the product to obtain manganese carbonate nanorods with a diameter of 50-100 nm and a length of 1-2 μm, and the manganese carbonate nanorods are single crystals.
