Preparation and Electrochemical Degradation of Ti/Nafion-Carbon Nanotubes/PbO₂ Electrode

By impregnating modified carbon nanotubes (CNTs) with Nafion in an ester solution, we prepared and characterized CNTs-Nafion composite materials using FT-IR. We fabricated a composite electrode, Ti/Nafion-CNTs/PbO 2 , through the coating and electro-deposition processes on a titanium substrate. Additionally, we characterized the physical and electrochemical properties of the composite electrode using techniques such as X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and cyclic voltammetry (CV). We analyzed the ability to generate hydroxyl radicals and the electrocatalytic oxidation of methyl orange by the composite electrode to assess its electrocatalytic oxidation capability. The results indicate that incorporating CNTs-Nafion composite material into the composite electrode can modify the electrode’s electrochemical properties and enhance its electrocatalytic oxidation capability.
