Özet

In this study, copper oxide/electrochemically reduced graphene oxide (CuxO/ERGO) nanocomposite film was deposited on Au electrode by the electrochemical method based on simultaneous deposition for the first time. XRD and XPS spectra of

CuxO/ERGO-Au electrode show that composite material contents CuO, Cu2O and graphene structures. The different shapes of copper oxide (such as nanoflowers and nanocubes) was seen in morphological analysis of CuxO/ERGO. The as-prepared CuxO/ERGO nanocomposite modified-Au electrode exhibited good electrocatalytic activity towards amperometric detection of dopamine [with high sensitivity (122.4 μA cm−2 mM−1) and low detection limit (12 × 10−9 mol.L−1)].
