[0034] The steps of the preparation method of the present invention are as follows:
[0035] Step 1: Dissolve the manganese salt evenly in the polymer aqueous solution, add an appropriate amount of potassium ferricyanide or sodium ferricyanide aqueous solution and stir at room temperature to form a manganese ferricyanide suspension; the polymer in the polymer aqueous solution in the present invention The substance can generate a certain force with manganese ions, and increase the viscosity of the solution, thereby inhibiting the generation rate of manganese ferricyanide, which is beneficial to the formation of cubic morphology.
[0036] The preferred molar ratio of manganese salt to potassium ferricyanide or sodium ferricyanide is controlled between 3:2-4:2. If there are too few manganese salts, excess potassium ferricyanide or sodium ferricyanide will react with the metal salt ions added subsequently to generate granular ferricyanides that are difficult to remove, which will ...

[0045] 1. Preparation of manganese ferricyanide template suspension
[0046] Dissolve 0.35g of polyvinylpyrrolidone in 10ml of absolute ethanol to form solution A; weigh 100mg of MnSO 4 ·H 2 O powder was uniformly dissolved in 10ml deionized water to form solution B. Slowly add solution B to solution A and continue stirring for 30 min, then add 10 ml of 0.03M potassium ferricyanide aqueous solution dropwise. After continuous stirring at room temperature for 12 hours, a suspension of manganese ferricyanide can be obtained.
[0047] 2. Preparation of nano hollow cobalt ferricyanide
[0048] 10ml 0.02M Co(NO 3 ) 2 The aqueous solution was added dropwise to the above suspension, stirred rapidly for 5 minutes, and then stood at room temperature for 10 hours to allow sufficient cation exchange reaction. Afterwards, centrifuge with deionized water at a rate of 6000r / min, and dry the obtained precipitate in an oven at 80°C for 18 hours to obtain a nano-hollow cobalt ferricyanide...
