Recently, the multiferroic material has fabulous attention in numerous applications owing to its excellent
electronic conductivity, unique mechanical property, and higher electrocatalytic activity, etc. In this
paper, we reported that the synthesis of bismuth ferrite (BiFeO3) nanosheets integrated functionalized
carbon nanofiber (BiFeO3 NS/F-CNF) nanocomposite using a simple hydrothermal technique. Herein,
the structural changes and crystalline property of prepared BiFeO3 NS/F-CNF nanocomposite were characterized
using Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), X-ray
diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Raman spectroscopy and X-ray photoelectron
spectroscopy (XPS). From this detailed structural evolution, the formation of nanosheets like
BiFeO3 and its nanocomposite with F-CNF were scrutinized and reported. Furthermore, the asprepared
BiFeO3 NS/F-CNF nanocomposite modified glassy carbon electrode (GCE) was applied for
electrochemical detection of catechol (CC). As expected, BiFeO3 NS/F-CNF/GCE shows excellent electrocatalytic
activity as well as 3.44 (F-CNF/GCE) and 7.92 (BiFeO3 NS/GCE) fold higher electrochemical redox
response for CC sensing. Moreover, the proposed sensor displays a wide linear range from 0.003 to 78.02 μM with a very low detection limit of 0.0015 μM. In addition, we have validated the real-time application
of our developed CC sensor in different water samples.
