Example Embodiment
[0021] Example 1
[0022] Weigh 99.5% of potassium persulfate according to the stoichiometric ratio of 1:1, analytically pure; 99% of manganese sulfate monohydrate, analytically pure; add the above-mentioned raw materials to the hydrothermal reactor, add deionized water to fully stir to make It dissolves; 2mL of concentrated sulfuric acid with a mass fraction of 95-98% is added to the hydrothermal reactor. At the beginning of the reaction, the concentration of sulfuric acid was 1 mol / L, and the concentration of potassium persulfate and manganese sulfate was 0.05 mol / L. The hydrothermal reaction kettle was placed in an oven at 110°C for 6h constant temperature reaction and then naturally cooled to room temperature. After washing the reaction product with deionized water and absolute ethanol for 5 times by centrifugation, it is tested that it does not contain SO 4 2- Afterwards, it is dried in an air atmosphere at a temperature of 60℃, and the product obtained is α-MnO 2 Micron hol...
