Sažetak
Graphene is emerging as a material with extraordinary physical and chemical properties. Due to its electrochemical properties, it offers vast potential applicability as an effective electrode material. With anodic pretreatment, it is possible to enhance the electrochemical sensing properties of graphene-modified electrodes. In the present study, electrochemical sensing properties of graphene-modified screen printed electrodes are investigated before and after anodic pretreatment of the electrode. The prepared electrode is electrochemically characterized by cyclic voltammetry and electrochemical impedance spectroscopy. The electrode surface is investigated by scanning electron microscopy, energy dispersive X-ray spectroscopy, and Raman spectroscopy. The heterogeneous electron transfer rate and capacitance is calculated from obtained cyclic voltammograms and electrochemical impedance spectroscopy respectively. Both values are compared before and after anodic pretreatment.
