Meticulous electrode design is pivotal in advancing greener and more sustainable electro‐organic synthesis practices. In this research, our team designed and synthesized a copper‐doped electrode on multiwalled carbon nanotubes (MWCNTs) and characterized it using Fourier transform infrared spectroscopy (FT‐IR), scanning electron microscopy (SEM), energy‐dispersive X‐ray spectroscopy (EDS), thermogravimetric analysis (TGA), Brunauer–Emmett–Teller (BET) analysis, X‐ray diffraction (XRD) analysis, X‐ray photoelectron spectroscopy (XPS), and cyclic voltammetry (CV) analysis. Subsequently, this electrode was utilized as a catalyst at the electrode surface, serving as a cathode in electro‐oxidation reactions in the presence of phenylacetylene, sodium azide (NaN3), and benzyl halide for the production of 1,2,3‐triazole derivatives under ambient temperature, within a 30‐min reaction time, and at atmospheric pressure, achieving an efficiency level ranging from good to excellent, specifically between 88% and 96%. The synthesized 1,2,3‐triazole derivatives were identified using proton nuclear magnetic resonance (1H NMR) spectroscopy, CHN elemental analysis, and melting point. In this paper, choline chloride/urea deep eutectic solvents (DES) serve multiple roles in the reaction mechanism. They function as solvents and co‐catalysts, generate weak bases, and provide numerous advantages in green chemistry. These advantages include low toxicity, reduced environmental risks, improved atom economy, and non‐volatility, making them safer alternatives to traditional organic solvents.
