摘要

In this study, we have reported the preparation of NiO/graphene (NiO/GR) nanocomposite for determination of Hvia a convenient solid reaction. The electrocatalytic behaviors towards Hare investigated by cyclic voltammetry and chronoamperometry in alkaline aqueous solution. Electrochemical results indicate that the NiO/GR nanocomposite exhibits a high peak current towards the oxidation of H Moreover, high electrocatalytic activity toward the oxidation of His observed with a low detection limit of 0.7664 μM, high sensitivity of 591 μA mM^-1 cm^-2, a wide linear range of 0.25-4.75 mM (R²=0.9971). Besides, the sensor presents many attractive features such as high stability and reproducibility.
