Beschreibungen/Notizen

• Copper oxide (CuO) nanoparticles were synthesized using the chemical and green method routes and doped with polyaniline (PANI) to form PANI/CuO ch and PANI/CuO gr nanocomposite. The microstructural properties of the nanocomposites were characterized by UV–Vis spectroscopy (UV), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy equipped with energy-dispersive X-ray spectroscopy (EDS) detector. The electrochemical behavior of the CuO ch , CuO gr , PANI/CuO ch , and PANI/CuO gr electrodes was investigated using cyclic voltammetry (CV), and square wave voltammetry (SWV), and the results showed an enhanced electrochemical catalytic activity toward dopamine (DA) on PANI/CuO gr electrodes. SWV was conducted for the determination of DA with a linear range from 26 to 95 μM and a low limit of detection (LOD) of 8.22 μM. A comparison between the PANI/CuO ch and PANI/CuO gr electrodes and other modified electrodes toward detection of DA are comparable with the reported literature results.
