Abstract

This study demonstrates a hydrothermal method to prepare perovskite-type potassium niobate (KNbO₃) through deep eutectic solvent (DES), which is further used as an electrode material for the determination of bisphenol A (BPA). The as-synthesized KNbO₃ was systematically characterized by different microscopic and spectroscopic techniques. The KNbO₃-modified electrode demonstrates excellent electrocatalytic activity for BPA compared to the pristine electrode. The enhanced performance of the proposed sensor is attributed to the numerous active sites, large electrochemical surface area, high electrical conductivity, and rapid electron transfer. The fabricated sensor shows a wide detection range (0.01-84.3 μM), a low limit of detection (0.003 μM), a high sensitivity (0.51 μA μM^-1 cm^-2), and good anti-interference abilities towards the BPA detection by linear sweep voltammetry method. Besides, it was successfully applied to determining BPA in food samples, demonstrating good practicability. This design paves a new way to fabricate efficient electrode material for various electrochemical applications using a DES medium.
