Examples
Embodiment 1
[0023] (1) Add nickel sulfate into distilled water in an amount of 0.1g / 40mL, and stir until the solution is clear;
[0024] (2) Add sodium tripolyphosphate in an amount of 0.1g / 40mL to the above solution, then add polyethylene glycol in an amount of 0.2g / 40mL, and stir until the solution is clear;
[0025] (3) Add sodium carbonate to the solution described in step (2) with stirring in an amount of 0.2g / 40mL, and then continue to stir for 10min to obtain a cloudy solution;
[0026] (4) Transfer the solution prepared in step (3) to the reactor, seal it, put it in an oven at 100°C, and react for 8 hours;
[0027] (5) After the reaction is over, cool the reactor to room temperature;
[0028] (6) Discard the supernatant in the reaction kettle, rinse the product with water and ethanol for 3±1 times, and then dry it in a 50°C oven for 6 hours. The powdery product obtained is the hollow spherical aggregate of nickel bicarbonate .
Embodiment 2
[0030] (1) Add nickel nitrate into distilled water in an amount of 1g / 40mL, and stir until the solution is clear;
[0031] (2) Add diethanolamine to the above solution in an amount of 1g / 40mL, then add cetyltrimethylammonium bromide in an amount of 1.5g / 40mL, and stir until the solution is clear;
[0032] (3) Add potassium bicarbonate to the solution described in step (2) with stirring in an amount of 1 g / 40 mL, and then continue stirring for 12 minutes to obtain a cloudy solution;
[0033] (4) Transfer the solution prepared in step (3) to the reactor, seal it, put it in an oven at 120°C, and react for 10 hours;
[0034] (5) After the reaction is over, cool the reactor to room temperature;
[0035] (6) Discard the supernatant in the reaction kettle, wash the product with water and ethanol for 3±1 times, and then dry it in a 60°C oven for 8 hours. The powdery product obtained is the hollow spherical aggregate of nickel bicarbonate .
Embodiment 3
[0037] (1) Add nickel acetate into distilled water in an amount of 1.5g / 40mL, and stir until the solution is clear;
