Abstract
Vanillin (Van), the main component is 3-methoxy-4-hydroxy-benzaldehyde. Vanillin is not only used in the food industry, but also widely applied in the field of medicine. A glassy carbon electrode (GCE) modified electrospun 2D molybdenum disulfide (MoS2) nanoparticles decorated carbon nanofibers (MoS2-CNF) were first applied for determining the amount of Van. The synthesized MoS2-CNF were characterized by scanning electron microscopy (SEM), Energy Dispersive Spectrometer(EDS), Electrochemical impedance technique(EIS). The electrochemical detection of Van was successfully conducted in 0.1 M phosphate solution (pH 10) and showed a good linear response in the range of 0.3 to 135 μM. The proposed electrode showed a good amperometric response signal toward Van and result in the determination of real sample.
