Embodiment 1
[0036] 1. Ingredients:
[0037] Mix 60ml of acetone and 40ml of ultrapure water evenly, mix 0.6651g of lithium carbonate and 0.5457g of vanadium pentoxide and disperse them in the above mixed solvent. Then join in the high-temperature and high-pressure reactor (volume is 250 milliliters) that has temperature measurement, pressure measurement device, seal.
[0038]2. Use high temperature and high pressure mixed solvent thermal system to implement constant temperature reaction:
[0039] Put the sealed reaction kettle into a muffle furnace, heat it to 280°C (the pressure inside the container reaches 9MPa), and keep the temperature constant for 2 hours.
[0040] 3. Cooling:
[0041] The reaction kettle was naturally cooled to room temperature (20° C. to 25° C.), and the reaction kettle was taken out from the muffle furnace.
[0042] 4. Washing:
[0043] The product was taken out from the reaction kettle, and the product was filtered through a vacuum filter (0.45 micron in aper...

[0062] 2. Use high temperature and high pressure mixed solvent thermal system to implement constant temperature reaction:
[0063] Put the sealed reaction kettle into a muffle furnace, heat it to 250°C (the pressure inside the container reaches 6MPa), and keep the temperature constant for 1 hour.
[0064] 3. Cooling:
[0065] The reaction kettle was naturally cooled to room temperature (20° C. to 25° C.), and the reaction kettle was taken out from the muffle furnace.
[0066] 4. Washing:
[0067] The product was taken out from the reaction kettle, and the product was filtered through a vacuum filter (0.22 micron in aper...
