Abstract:

The nickel hydroxide-graphene[Ni(OH)2-graphene] nanostructures were fabricated by facile microwave method, and the structure and electrocatalytic activities of the synthesized nanostructures were characterized via scanning electron microscopy(SEM), X-ray photoelectron spectroscopy(XPS), X-ray powder diffraction(XRD), energy-dispersive spectroscopy(EDS), electrochemical impedance spectroscopy(EIS) and cyclic voltammetry. The results indicated that the Ni(OH)2-graphene nanotructures exhibited a higher electrocatalytic activity than the Ni(OH)2 nanoparticles. A glucose nonenzyme sensor was developed based on the Ni(OH)2-graphene nanotructures. The sensor exhibited a low detection limit of 2 μmol/L, a wide linear range from 0.01 to 7.5 mmol/L, and a high sensitivity of 174.7 μA·cm-2·mmol·L-1. In addition, the sensor exhibited excellent stability and selectivity for the glucose detection, and it could be used to analyze real samples.
