Highly sensitive Electrochemical Sensor based on Perovskite type PrCoO3 for the detection of carbendazim

In this work, the Carbendazim fungicide was detected using an electrochemical sensing platform based on the Praseodymium cobalt oxide (PrCoO3) compound, which was synthesized using a simple co-precipitation process. Field emission scanning electron microscopy (FESEM), energy dispersive X-ray (EDX), powder X-ray diffraction (XRD), and X-Ray photoelectron spectroscopy (XRPS) were used to classify the synthesized content. The electrical conductivity of PrCoO3 was investigated by using electrochemical impedance spectroscopy. PrCoO3 compound were used to detect CBZ. Cyclic voltammetry and differential pulse voltammetry were used to scrutinize the electrochemical performance of CBZ on PrCoO3/GCE. The electrocatalytic operation of the prepared sensor against CBZ was exceptional. Additionally, under streamlined laboratory conditions, the PrCoO3 sensor has a higher sensitivity of 9.6619 A M1 cm2, a lower detection limit (LOD) of 2 nM, and a linear range of 0.001 to 84 M for CBZ detection. Furthermore, the effect of storage time on the PrCoO3 sensor's CV response reveals a higher stability. The as-fabricated sensor was successfully used to detect the CBZ level in orange juice and river water due to its exceptional analytical benefits.
