Embodiment Construction
[0025] A production method of an indium-doped cobalt-MOF derivative for preparing capacitor electrodes of the present invention is carried out according to the following steps:
[0026] Step 1. Dissolve 1.6 mmol of cobalt nitrate in 80 mL of methanol and stir for 30 min, then add 0.25 mmol of indium nitrate and continue to stir for 40 min to obtain solution A;
[0027] Step 2. Dissolve the imidazole ligand in 80 mL of a liquid with a volume ratio of methanol to water of 10:1 to a final concentration of 1.0 mol L -1 , and stirred for 30min to obtain solution B;
[0028] Step 3. Quickly mix solution A and solution B, stir evenly to form solution C, seal and let stand at room temperature for 20 h;
[0029] Step 4. Centrifuge the solution C and collect the precipitate, wash it with absolute ethanol, put it into a vacuum drying oven at 80°C for drying for 20 hours, and obtain a dry powder;
[0030] Step 5. Lay the dry powder evenly into the porcelain boat, the thickness of the ti...
