Abstract
Herein, we describe the fabrication of NiO decorated single wall carbon nanotubes
(NiO-SWCNTs) nanocomposites using the precipitation method. The synthesized NiO-SWCNTs
nanocomposites were characterized by X-ray diffraction (XRD) and Transmission electron microscopy
(TEM). Remarkably, NiO-SWCNTs and 1-butylpyridinium hexafluorophosphate modified carbon paste
electrode (CPE/NiO-SWCNTs/BPrPF6) were employed for the electrochemical detection of vanillin. The
vanillin sensor showed an ultra-high sensitivity of 0.3594 µA/µM and a low detection limit of 0.007
µM. In the final step, the NiO-SWCNTs/BPrPF6 was used as the suitable tool for
food analysis.
