Synthesis and Characterization of Electrospun Nickel Doped Cobalt(II, III) Nanofibers with Application to Maltose Determination

Nickel doped cobalt(II, III) composite nanofibers were prepared by an electrospinning and sequential calcination process, and characterized by scanning electron microscopy, energy dispersive spectrometry, and X-ray diffraction. An electrospun nickel doped cobalt(II, III) modified carbon paste electrode was used for maltose determination using cyclic voltammetry and amperometry. Under the optimized conditions, a linear response was obtained between 0.2 and 100.0 µM, with a low detection limit of 32.5 nM.
