▎ 摘  要

NOVELTY - Method for preparing iron-nitrogen doped carbon nanotube electrode comprises dissolving polymer and zinc salt in a solvent, electrostatic spinning to obtain zinc/polymer fiber, and drying to remove the solvent, soaking zinc/polymer fiber in the nitrogen-containing organic ligand solution and the mixed solution of ferrous salt and zinc salt successively, and repeating the process many times to obtain the metal-organic framework/polymer fiber that grows layer by layer, immersing the metal-organic framework/polymer fiber in a solvent, dissolving the polymer therein, and then washing and drying to obtain a metal-organic framework nanotube with a three-dimensional structure, carbonizing metal-organic framework nanotubes to obtain iron-nitrogen-doped carbon nanotubes with a three-dimensional structure, uniformly mixing the iron-nitrogen-doped carbon nanotubes, conductive agent, and binder and coating and set on the fluid and drying. USE - The electrode is useful for salt water desalination in capacitive deionization technology (claimed). ADVANTAGE - The electrode has large desalination capacity, strong long-term desalination stability and fast desalination rate.
