通过电化学沉积法在掺铟氧化锡(ITO)的玻璃基板上制备NiO构建非酶葡萄糖传感器。氯化胆碱-脲离子液体用作电沉积介质,探究了沉积电压,离子液体粘度和镍离子浓度对氧化镍薄膜葡萄糖传感性能的影响。用扫描电子显微镜(SEM)和X射线衍射仪(XRD)对薄膜的物相鉴定和形貌表征。采用循环伏安法(CV)和时间-电流曲线(i-t)评估传感器的性能,结果表明,其中沉积电压3.9V,离子液体和乙醇比为1 ∶ 2,镍离子浓度为0.2 mol/L时薄膜对葡萄糖具有最佳检测性能,其线性范围为4 μmol/L~256 μmol/L和312~528 μmol/L,其灵敏度分别为496.03 μA/(mmol/L·cm~2)和67.59 μA/(mmol/L·cm~2)。该电化学传感器选择性、重现...

NiO was prepared on a glass substrate doped with indium tin oxide(ITO)by electrochemical deposition to construct an enzyme-free glucose sensor.Choline chloride-urea ionic liquid was used as the electrodeposition medium,and the influence of deposition voltage,ionic liquid viscosity,and nickel ion concentration on the glucose sensing performance of nickel oxide film was investigated.Scanning electron microscope(SEM)and X-ray diffractometer(XRD)were used to identify the composition and morphology of the film.Cyclic voltammetry(CV)and time-current ...
