Interfacial electronic coupling in pyrochlore Bi₂Sn₂O₇/functionalized carbon nanofiber composites for electrochemical detection of the acetylcholinesterase inhibitor Bendiocarb

Bendiocarb (BDC) can have bad effects on health and the environment when it gets into the body or the environment through skin contact or eating. These effects can include problems with the liver, kidneys, lungs, and hormones. So, it is very important to Scrutinize the levels of BDC residue. Therefore, we made Bi₂Sn₂O₇/ f -CNF, a composite of bismuth stannate (Bi₂Sn₂O₇) and functionalized carbon nanofibers ( f -CNF), to make it easier for electrons to move through the electrochemical detection of BDC. Cyclic voltammetry (CV), differential pulse voltammetry (DPV), and electrochemical impedance spectroscopy (EIS) were used to study the structure and electrochemical properties of Bi₂Sn₂O₇/ f -CNF/GCE. The composite was very effective at electrocatalyzing BDC. It could detect BDC in a range of 0.01–947 µM, with a low detection limit of 0.1327 µM, a low detection quantification of 0.4079 µM, and a sensitivity of 0.3100 µA µM⁻¹ cm⁻². Scrutinize on real samples, like spinach and cabbage leaves, showed that the detection worked well because it had high recovery rates. Bi₂Sn₂O₇/ f- CNF/GCE is a quick, accurate, and sensitive.
