Method for preparing metal-organic framework catalytic electrode through degradation of PET waste plastics and application of metal-organic framework catalytic electrode

The invention belongs to the technical field of PET waste plastic recycling, and particularly relates to a method for preparing a metal-organic framework catalytic electrode through degradation of PET waste plastic and application of the metal-organic framework catalytic electrode. The preparation method comprises the following steps: dissolving metal salt in deionized water to form a solution A; uniformly mixing the organic solvent with the solution A to form a solution B; pET waste plastics are added into the solution B, the pretreated NF is immersed in the solution B, and a hydrothermal reaction is carried out; and after the reaction is finished, washing and drying the solvothermal product to obtain the MOF catalytic material containing the corresponding metal ions. A simple one-step hydrothermal synthesis method is adopted, and waste PET plastic and cheap metal salt are used for synthesizing the efficient water electrolysis catalytic electrode which can be directly used as a working electrode on foamed ni
