Abstract
AbstractElectrocodeposition of nickel oxide (NiOx) and polyaniline (PANI) was conducted through cyclic voltammetric scans in an aqueous solution of NiSO4 and aniline. Characterizations of the obtained NiOx/PANI composite film by XRD and FTIR indicated that the film composed of NiOx and PANI, in which nickel oxide was in the form of Ni2O2(OH). Ni(II)/Ni(III) redox couple appeared at 0.30 V versus SCE on the cyclic voltammogram (CV) of the composite film. Electrooxidations of glucose and fructose occurred at the potential where nickel oxide existed in higher oxidation state. The anodic current densities at 0.46 V for the electrooxidations were linearly dependent on the concentration of polyhydroxyl compounds from 1 to 100 mM for glucose and 10 to 100 mM for fructose, respectively. © 2007 Wiley Periodicals, Inc.
