Abstract:
Electrochemical detection of glucose in alkaline solution was performed on La0.88Sr0.12MnO3 (LSMO) nanofibers modified carbon paste electrode. Perovskite-type oxide LSMO nanofibers were prepared by an electrospinning and calcination process. The morphologies, structures, and electrochemical behavior of the nanofibers were characterized by scanning electron microscope, energy dispersive spectrometer, X-ray diffraction, Fourier transform infrared spectrum, and cyclic voltammetry. The modified electrode shows excellent electrocatalytic activity toward glucose. Under optimal conditions, the linear response was obtained in the range of 0.05-100 μM with high sensitivity and rapid response.
