Embodiment 1
[0019] (1) Take ferrous sulfate heptahydrate (FeSO 4 ·7H 2 O) and manganese sulfate monohydrate (MnSO 4 ·H 2 O) and mix, add an appropriate amount of distilled water to dissolve, so that the concentrations of iron ions and manganese ions in the iron-manganese mixed solution are both 0.10 mol / L.
[0020] (2) Measure 100 mL of the iron-manganese mixed solution obtained in step (1) and place it in a 500 mL reactor, add 200 mL of 2.67 mol / L ammonia solution dropwise to it while stirring at a constant temperature of 25 °C, and stir The speed is 350 rpm; after the ammonia water is added dropwise, the stirring reaction is continued for 3 hours, and the stirring is stopped; then the reactor is placed at room temperature and aged for 12 hours; finally, the precipitate is filtered, washed, and freeze-dried to obtain Precursor powder.
[0021] (3) Measure 15 mL of ethanol aqueous solution (the volume ratio of absolute ethanol to distilled water is 1:2), and add 0.1 g of the precursor...
