Hierarchical macro-mesoporous Ni(OH)(2) were prepared by hydrothermal treatment of Ni(NO3)(2) with dicyandiamide. This Ni(OH)(2) nanostructure can be transformed to mesoporous NiO via calcination at 300 degrees C. The structure, morphology and textural properties of the as-synthesized Ni(OH)(2) and NiO were characterized. The electrochemical property and electrochemical sensing performance toward glucose detection were investigated. Owing to the unique macro-mesoporous structure, the Ni(OH)(2) nanostructure could provide amperometric sensing of glucose with wide linear range (0.01-8.3 mM), high sensitivity of 243 mu A mM cm(-2) and low detection limit of 1 mu M. Moreover, this glucose sensor also exhibited excellent stability, good selectivity and reproducibility. (C) 2014 The Electrochemical Society. All rights reserved.
