The usage of a ytterbium oxide nanorod/carbon nanofiber (Yb2O3/f-CNF) hybrid nanocomposite for the electrochemical detection of carbendazim (CBZ) fungicide is demonstrated for the first time in this study. Various physicochemical methods such as Field Emission Scanning Electron Microscopy (FE-SEM), Transmission electron microscopy (TEM), and X-ray diffraction (XRD) spectroscopy have been used to confirm the formation of Yb2O3, f-CNF, and Yb2O3/f-CNF composite. Different electrode electrochemical characteristics for the detection of CBZ were investigated using cyclic voltammetry and differential pulse voltammetry. Compared to Yb2O3 and f-CNF, the Yb2O3/f-CNF nanocomposite had the most significant electrocatalytic activity for CBZ oxidation. The designed sensor has a low detection limit (6 nM) and an extensive linear range (50 nM to 3035 µM) with excellent sensitivity (0.2899 µA µM−1 cm−2). Furthermore, the sensor has shown outstanding stability, anti-interference ability, reproducibility, repeatability, and practicability. In addition, these sensor electrodes are simple to make, inexpensive, portable, and effective in detecting CBZ fungicide residues in food and the environment.
