Embodiment 1
[0038] Weigh 1.5710g of methyl orange and dissolve it in 100mL of water to form a transparent solution, quickly add 0.7780g of anhydrous FeCl 3 , keep at 1200r / min for 30min to form a uniform fibrous composite suspension, and use the fibrous composite as a self-degradation template.
[0039] Add 0.84mL of Py monomer dropwise to the above-mentioned fibrous composite suspension, and keep it under magnetic stirring at 1200r / min at a temperature of 25°C for 24h, so that Py is uniformly aggregated on the surface, and the Buchner funnel is used to reduce After pressure filtration, wash with secondary water and absolute ethanol several times until the filtrate becomes colorless to remove excess methyl orange, and then dry the filtered product in an oven at 60°C for 12 hours to obtain PPy. Finally the PPy solid in N 2 Under the atmosphere, the temperature was raised to 800°C at a rate of 5°C / min and kept for 2 hours to obtain black N-CNTs.
