Electrospun MoS2 composite carbon nanofibers for determination of vanillin

Electrospun molybdenum disulfide (MoS 2 ) nanoparticles composite carbon nanofibers (MoS 2 -CNF) were first applied for determining the amount of Vanillin . The synthesized MoS 2 -CNF was characterized by scanning electron microscopy (SEM), Raman, X-Ray diffraction (XRD) and Electrochemical impedance technique (EIS). The electrochemical detection of vanillin was successfully conducted in 0.1 M Phosphate Buffer (pH 10) and showed a good linear response in the range of 0.3 to 135 μM and the detection limit reached 0.15 μM. The sensor showed a good amperometric response signal toward vanillin and result in the determination of real sample.
