Embodiment 1
[0021] The specific preparation process is as follows: 1) 0.05g of silver nitrate, 0.2g of polyvinylpyrrolidone (PVP) and 0.02g of acetate were sequentially added into 20mL of water and stirred. Subsequently, the mixed solution was stirred at room temperature for 30 min, and 0.25 mL of pyrrole monomer and 10 mL of 0.3 mol / L ferric chloride aqueous solution were respectively added through a peristaltic pump at a speed of 600 μL / min, and the reaction was continued for 2 h. The obtained product was washed more than 3 times, and then added to 20 mL of 0.6 mmol / L potassium permanganate solution, and reacted at 120° C. for 2 h. 2) The synthesized Ag / PPy / MnO 2 Composite nanomaterials for cleaning and Ag / PPy / MnO 2 The preparation of the granules, the specific method is: the obtained product is washed more than 3 times by centrifugation at 10,000 rpm for 10 minutes with ethanol, then it is dispersed in absolute ethanol, and its mass fraction reaches 60%, and it is passed through an ov...

[0023]The specific preparation process is as follows: 1) 0.5g of silver nitrate, 2.0g of polyvinylpyrrolidone (PVP) and 0.2g of acetate were sequentially added into 200mL of water and stirred. Subsequently, the mixed solution was stirred at room temperature for 30 min, and 2.5 mL of pyrrole monomer and 100 mL of 0.3 mol / L ferric chloride aqueous solution were added through a peristaltic pump at a speed of 600 μL / min, and the reaction was continued for 2 h. The obtained product was washed more than 3 times, and then added to 200 mL of 0.6 mmol / L potassium permanganate solution, and reacted at 120° C. for 2 h. 2) The synthesized Ag / PPy / MnO 2 Composite nanomaterials for cleaning and Ag / PPy / MnO 2 The preparation of the granules, the specific method is: the obtained product is washed more than 3 times by centrifugation at 10,000 rpm for 10 minutes with ethanol, then it is dispersed in absolute ethanol, and its mass fraction reaches 60%, and it is passed through an oven at 60 Dry ...
Embodiment 3
[0025] The specific preparation process is as follows: 1) 0.08g of silver nitrate, 0.32g of polyvinylpyrrolidone (PVP) and 0.032g of acetate were sequentially added into 30mL of water and stirred. Subsequently, the mixed solution was stirred at room temperature for 30 min, and 0.4 mL of pyrrole monomer and 16 mL of 0.3 mol / L ferric chloride aqueous solution were respectively added through a peristaltic pump at a speed of 600 μL / min, and the reaction was continued for 2 h. The obtained product was washed more than three times, and then added to 32 mL of 0.6 mmol / L potassium permanganate solution, and reacted at 120° C. for 2 h. 2) The synthesized Ag / PPy / MnO 2 Composite nanomaterials for cleaning and Ag / PPy / MnO 2 The preparation of the granules, the specific method is: the obtained product is washed more than 3 times by centrifugation at 10,000 rpm for 10 minutes with ethanol, then it is dispersed in absolute ethanol, and its mass fraction reaches 60%, and it is passed through ...
