通过将钛片在含镍溶液中水热处理,在钛基体上直接生长Ni(OH)2纳米片阵列,并用于电化学检测葡萄糖。用X射线衍射(XRD)和扫描电镜(SEM)对样品进行了表征。研究了Ni(OH)2纳米片/钛片在NaOH溶液中的电化学性能。结果表明,该电极对葡萄糖的氧化具有良好的电催化作用,它对葡萄糖响应的线性范围为4.5×10-5～1.05×10-3mol/L,检出限为5μmol/L(S/N=3)。
The Ni (OH) 2 nanosheet arrays were directly grown on a titanium substrate by hydrothermal treatment of titanium flakes in a nickel-containing solution and used to electrochemically detect glucose. The samples were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The electrochemical performance of Ni (OH) 2 nanosheet / Ti plate in NaOH solution was studied. The results showed that the electrode had good electrocatalytic activity for the oxidation of glucose. The linear range of its response to glucose was 4.5 × 10-5 ~ 1.05 × 10-3 mol / L with the detection limit of 5μmol / L (S / N = 3).
