A novel amperometric nonenzymatic glucose sensor based on Au-doped NiO nanobelts has been successfully fabricated and applied to nonenzymatic glucose detection. Its electrochemical behavior towards the oxidation of glucose was compared with NiO nanofibers and Au microparticles prepared with a similar procedure. The NiO-Au hybrid nanobelts modified electrode displays greatly enhanced electrocatalytic activity towards glucose oxidation, revealing a synergistic effect between the matrix NiO and the doped Au. The as-prepared NiO-Au nanobelts based glucose sensor displays significantly lower onset potential, lower detection limit, higher sensitivity, and wider linear range than that of pristine NiO nanofibers modified electrode. Moreover, Au nanoparticles distributed in NiO nanofibers enabled amperometric glucose detection with insignificant interference from ascorbic acid and uric acid. These results indicate that the NiO-Au hybrid nanobelt is a promising candidate in the development of highly sensitive and selective nonenzymatic glucose sensors. |
