Preparation and Glucose Sensing Property of Core-shelled Nikel Oxide/Carbon Microspheres
By using carbon spheres as a template, precursor Ni(OH) sub(2)/C were prepared by a hydrothermal synthesis technology with the reaction of hexahydrate nickel chloride and urea.

description | By using carbon spheres as a template, precursor Ni(OH) sub(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 1.4 mu m, 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 31.37 m A/(mmol times L super(-1) times cm super(2)) better than that of NiO, among the linear range of 2-1279 mu mol/L with detecting limit at 2 mu mol/L. Furthermore, the core-shelled NiO/C microspheres exhibit good stability and anti-interference ability. |
