Highly performed electrode possessed excellent electrocatalytic performance for electrochemical oxidation technology remains a huge challenge. Here, we prepared a durable metal–organic frameworks (MOF)-derived materials doped PbO₂ electrode to improve the electrocatalytic performance and service life. The prepared UiO-66 derived ZrO₂-C nanoparticles doped PbO₂ composite electrode had more active sites, improved conductivity, higher hydroxyl radical (OH) generation capacity, and excellent stability. The composite PbO₂ electrode with ZrO₂-C nanoparticles doping amount of 4 g L^-1 had the best electrocatalytic activity, and the 2, 4, 6-trinitrophenol (TNP) removal rate was up to 94.48% after 140 min of electrolysis, whereas that of pure PbO₂ was only 68.33%. Besides, the degradation conditions were further optimized and the electrochemical oxidation degradation pathway of TNP was proposed. Thus, we can conclude that MOF-derived doped PbO₂ anode has greater promising application potential in the electrocatalytic degradation of phenolic compounds in wastewater.
