Cylindrical rod‐shaped copper succinate nanoparticles were prepared using the electrochemical method. Taguchi robust design was applied to optimize experimental parameters such as succinic ion concentration (Co), current applied (Iap), and pH (pH). The obtained copper succinate nano‐rods were further thermally treated at different temperatures to produce copper oxide (CuO) nano‐disks. At optimum conditions of Iap = 0.5 A, pH = 7, and Co = 0.25, the maximum productivity of copper nanoparticles before and after calcination at 500 °C was 1.53 g and 1.06 g, respectively. Products were characterized by Fourier transform infrared spectroscopy (FTIR), X‐ray diffraction (XRD), scanning electron microscopy (SEM), and UV‐visible spectrophotometry to determine their various physicochemical characteristics.
