- Abstract
In this report, hierarchical cobalt hydroxide [Co(OH)2] hollow spheres composed of nanosheets were synthesized by fast etching of polycrystalline cuprous oxide and were then ap- plied for the nonenzymatic electrochemical detection of glucose. The fabricated hierarchical Co(OH)2 nanosheet hollow spheres were characterized by X-ray photoelectron spectro scopy, X-ray diffraction, field-emission scanning electron microscopy, transmission electron microscopy, and selected area electron diffraction. The electrochemical performance of the hierarchical Co(OH)2 nanosheet hollow spheres modified electrode to detect glucose was investigated by cyclic voltam metry. These sensors exhibited excellent electrocatalytic activity toward glucose, with a response time of less than 5 s. The calibration plot is linear over the wide concentration range of 1 µM to 0.13 mM, with a high sensitivity of 925.21 µA mM-1 cm-2, a correlation coefficient of 0.9942, and a detection limit of 0.93 µM (signal to noise: 3). The results demonstrate that hierarchical Co(OH)2 nanosheet hollow spheres play a vital role in the development of electrochemical sensors for nonenzymatic glucose detection.
