Embodiment 1

[0027] Preparation of polyaniline nanoflower-modified carbon cloth electrodes:

[0028] The purchased commercial carbon cloth was cut into a size of 1cm×2cm, and then assembled with a 12cm titanium wire to form an electrode, immersed in deionized water and ultrasonicated for 30min to drive away the air bubbles on the surface. Add tartaric acid aqueous solution (0.8mmol / 9mL water) and aniline monomer (5mL, 0.8M, 4mmol) successively to a 20cm glass bottle, and ammonium persulfate (APS) aqueous solution (2mL, 0.8M, 1.6mmol) is directly Add the above solution. Then, the ultrasonically treated carbon cloth connected with titanium wires was quickly immersed in the above-mentioned glass bottle, and finally the glass bottle was left standing for 12 hours at 0°C. The modified carbon cloth was taken out, washed three times with deionized water, and air-dried to obtain the polyaniline nanoflower-modified carbon cloth electrode.

Embodiment 2

[0030] The purchased commercial carbon cloth was cut into a size of 1cm×2cm, and then assembled with a 12cm titanium wire to form an electrode, immersed in deionized water and ultrasonicated for 30min to drive away the air bubbles on the surface. Add tartaric acid aqueous solution (0.8mmol / 8mL water) and aniline monomer (5mL, 0.8M, 4mmol) into a 20cm glass bottle successively, and ammonium persulfate (APS) aqueous solution (3mL, 0.8M, 2.4mmol) is directly Add the above solution. Then, the ultrasonically treated carbon cloth connected with titanium wires was quickly immersed in the above-mentioned glass bottle, and finally the glass bottle was left standing at 5° C. for 14 h. The modified carbon cloth was taken out, washed three times with deionized water, and air-dried to obtain the polyaniline nanoflower-modified carbon cloth electrode.

Embodiment 3

[0032] The purchased commercial carbon cloth was cut into a size of 1cm×2cm, and then assembled with a 12cm titanium wire to form an electrode, immersed in deionized water and ultrasonicated for 30min to drive away the air bubbles on the surface. Add tartaric acid aqueous solution (0.8mmol / 7mL water) and aniline monomer (5mL, 0.8M, 4mmol) to a 20cm glass bottle successively, and ammonium persulfate (APS) aqueous solution (4mL, 0.8M, 3.2mmol) is directly Add the above solution. Then, the ultrasonically treated carbon cloth connected with titanium wires was quickly immersed in the above-mentioned glass bottle, and finally the glass bottle was left standing for 16 hours at 0°C. The modified carbon cloth was taken out, washed three times with deionized water, and air-dried to obtain the polyaniline nanoflower-modified carbon cloth electrode.

Abstract

The invention discloses preparation method and application of a polyaniline nanometer flower-modified carbon cloth electrode, and belongs to the technical field of an electrode material. Carbon clothis used as a substrate, in-situ polymerization of polyaniline is performed on a surface of the carbon cloth by controlling a proportion between an aniline monomer and ammonium persulfate, and the polyaniline nanometer flower-modified carbon cloth electrode is obtained after washing and drying. The polyaniline nanometer flower-modified carbon cloth electrode obtained by preparation can be used as amicrobial fuel cell positive electrode and is endowed with extremely high current density and power density compared with a carbon cloth electrode which is not modified. The preparation process is simple and is low in cost, a microbial fuel cell is good in power generation performance, and the preparation method has very important significance to practical application of the microbial fuel cell.

Description

technical field [0001] The invention relates to a novel electrode, in particular to a carbon cloth electrode modified by polyaniline nanoflowers, a preparation method and application thereof, and belongs to the technical field of electrode materials. Background technique [0002] Polyaniline (PANI) is a very important conductive polymer, which has a wide range of applications due to its variety of morphology and structure. At the same time, PANI has good electrochemical redox activity, electrocatalysis and good biocompatibility, and the quinone structure in PANI can accelerate the electron transfer process on the anode surface. Therefore, the use of PANI for electrode modification has great application prospects. [0003] Microbial Fuel Cells (MFCs) is a technology that uses microorganisms to degrade organic matter to generate electricity. This technology has the dual functions of wastewater treatment and electric energy recovery. Its appearance is a major innovation to th...
