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 mu mol/L, a wide linear range from 0. 01 to 7. 5 mmol/L, and a high sensitivity of 174. 7 mu A .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.
