Description
Summary:Glucose nonenzymatic detection is of significance in the fields of biological, environmental, food monitoring, and clinical analysis. By employing mesoporous NiCo 2 O 4 nanowires as electrochemical sensor, highly sensitive nonenzymatic detection of glucose has been realized. The NiCo 2 O 4 nanowires were synthesized via a facile hydrothermal method and subsequent thermal treatment. Their crystalline structures were analyzed by X-ray diffraction, and morphologies were characterized using scanning electron microscopy and transmission electron microscopy. The porous characteristics and real surface areas of the synthesized NiCo 2 O 4 were studied by Brunauer–Emmett–Teller method. Electro-catalytic oxidation of glucose on the NiCo 2 O 4 electrode was investigated by cyclic voltammetry, linear sweep voltammetry, and amperometry. The nonenzymatic sensor based on NiCo 2 O 4 exhibited superior performance for glucose detection, with a low detection limit and excellent sensitivity.
