The carbon nano tube electrode is prepared by regulating the ratio of the carbon nano tube to polytetrafluoroethylene to metal used for modification, the prepared electrode has the advantages of simple preparation process, high strength, long service life, good conductivity and the like, and the dechlorination rate can reach more than 85% after reaction occurs for a period of time when the electrode is applied to electrochemical degradation of triclosan-containing solution.

Description

technical field [0001] The invention relates to a method for preparing a carbon nanotube electrode. The electrode has a simple preparation process and stable performance. After modification, it can be used for electrolyzing persistent organic pollutants, especially some chlorinated organic substances, and is an excellent electrode. Background technique [0002] In 1991, Japanese scientist Iijima used a high-resolution electron microscope to study vacuum arc-evaporated graphite, and discovered a multi-layered tube of carbon with nanometer dimensions, that is, multi-walled carbon nanotubes. This discovery has attracted extensive attention from the physics, chemistry, material science and high-tech industry departments, and has set off another research climax after C60. The unique physical and chemical properties of carbon nanotubes, such as extremely high mechanical strength, good adsorption capacity and strong microwave absorption energy, are increasingly recognized by people...
