Embodiment 1
[0035] The preparation method of the present embodiment comprises the following steps:
[0036] Step 1. Add 0.01mol pyrrole, 0.01mol aniline and 0.02mol hydrochloric acid into 200mL deionized water, and then ultrasonically disperse for 30min to obtain mixed solution A;
[0037] Step 2: Add 0.02mol hydrogen peroxide and 0.2mmol silver nitrate into 200mL deionized water, and then ultrasonically disperse for 30min to obtain mixed solution B;
[0038]Step 3. Add the mixed solution B obtained in step 2 dropwise to the mixed solution A obtained in step 1 and stir evenly, then react under microwave-assisted conditions to obtain a slurry containing precipitation; the power of the microwave Be 100W, the time of described reaction is 120min;
[0039] Step 4, centrifuge the slurry obtained in step 3 and collect the precipitate, then wash the precipitate with ethanol and distilled water respectively, then centrifuge and collect the precipitate until the centrifuged supernatant is colorle...
Embodiment 2
[0042] The preparation method of the present embodiment comprises the following steps:
[0043] Step 1. Add 0.02mol of pyrrole, 0.02mol of aniline and 0.2mol of hydrochloric acid into 200mL of deionized water, and then ultrasonically disperse for 30min to obtain mixed solution A;
[0044] Step 2: Add 0.04mol ammonium persulfate, 0.01mol Tween-80, and 0.4mmol ferrous chloride into 200mL deionized water, and then ultrasonically disperse for 30min to obtain mixed solution B;
[0045] Step 3. Add the mixed solution B obtained in step 2 dropwise to the mixed solution A obtained in step 1 and stir evenly, then react under microwave-assisted conditions to obtain a slurry containing precipitation; the power of the microwave Be 100W, the time of described reaction is 120min;
[0046] Step 4, centrifuge the slurry obtained in step 3 and collect the precipitate, then wash the precipitate with ethanol and distilled water respectively, then centrifuge and collect the precipitate until the...
Embodiment 3
[0049] The difference between this embodiment and embodiment 2 is that: the acid described in step 1 is sulfuric acid; the oxidant described in step 2 is potassium persulfate, and the power of the microwave described in step 3 is 300W.
