Synthesis of Nickel Oxide Nanomaterials for Electrochemical Detection of Glucose in Different Alkaline Environments
摘要
A hydrothermal method for synthesizing nickel oxide nanomaterials (NiO) is reported. The synthesized nanomaterials were successfully characterized by x-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), energy-dispersive spectrometry (EDS), and x-ray photoelectron spectroscopy (XPS). The electrochemical properties of the NiO/glassy carbon electrode (GCE) with respect to glucose were studied by electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), amperometric I–t curve (I–t), and anti-interference and stability tests. Different alkaline environments, namely 0.1M KOH and 0.1M NaOH solutions, were employed to compare the electrochemical glucose detection performance of NiO/GCE.
