核壳结构氧化镍/碳微球的制备及葡萄糖传感性能
Preparation and Glucose Sensing Property of Core-shelled Nikel Oxide/Carbon Microspheres
摘要
Abstract
By using carbon spheres as a template, precursor Ni(OH)2/C were prepared by a hydrothermal synthesis technology with the reaction of hexahydrate nickel chloride and urea. And then the precursor was calcinated in pure nitrogen to obtain core-shelled NiO/C microspheres. Scanning electron microscope (SEM), X-ray diffraction (XRD), X-ray energy dispersive (EDX), and the thermo gravimetric analyzer (TGA) were used to characterize morphology and structure of the samples. Results show that the NiO/C microspheres have core-shell structure with diameter around 1.4μm, carbon sphere as the core, and cubic NiO nanoplates with thickness of 50 nm as the shell. Electrochemical behavior and sensing property of core-shelled NiO/C microspheres were studied via cyclic voltammetry and amperometric method. The results displayed that glucose sensitivity of the NiO/C is 31.37mA/(mmol·L-1·cm2)better than that of NiO, among the linear range of 2–1279μmol/L with detecting limit at 2μmol/L. Furthermore, the core-shelled NiO/C microspheres exhibit good stability and anti-interference ability.关键词
