Abstract
- The flexible, free-standing and durable highly rough NiS/rGO composite paper electrode was prepared with a simple electrochemical deposition of NiS structures on the surface of the rGO paper electrode. NiS/rGO composite paper electrode was characterized by using scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), Xray diffraction (XRD), Raman spectroscopy and electrochemical impedance spectroscopy (EIS) techniques. Asprepared NiS/rGO composite paper was used for the electrochemical detection of ascorbic acid (AA). The rough and the ball-like NiS nanostructures on the rGO paper electrode surface greatly increased the catalytic performance of the paper electrode by providing a large active surface area. AA was detected on NiS/rGO composite paper with a wide linear range from 1.0 to 800 μM, a low detection limit of 0.7 μM (S/N=3) and a high sensitivity. Besides, the electrochemical tests showed that the composite paper electrode is very stable, flexible and durable at the atmospheric conditions. [ABSTRACT FROM AUTHOR]
