Abstract

A novel nonenzymatic hydrogen peroxide (H ₂O ₂) sensor was fabricated, based on nickel hydroxide (Ni(OH) ₂) modified silicon nanowires (SiNWs) electrode. The Ni(OH) ₂/SiNWs electrode consisted of SiNWs as backbone prepared by a chemical etching process and a Ni(OH) ₂ coating layer deposited by an electroless plating technique. The morphology of the Ni(OH) ₂/SiNWs electrode was characterized via scanning electron microscope (SEM) and X-ray diffraction (XRD). The analytical performances of the Ni(OH) ₂/SiNWs electrode for determination of H ₂O ₂ were investigated by cyclic voltammetry (CV) and amperometry. The prepared electrode exhibited an ultrahigh sensitivity of 3.31 mA mM ^-1 cm ^-2 with a detection limit (S/N = 3) of 3.2 μM. In addition, the electrode also exhibited superior stability, anti-interference and selectivity. These features demonstrated the Ni(OH) ₂/SiNWs electrode was suitable for detection of hydrogen peroxide.
