Development of an Electrochemical Platform Based on Nanoplate-like Zirconium Phosphate for the Detection of Furazolidone

Inorganic nanomaterials have gained significant attention as an efficient electrocatalyst for several electrochemical applications in the past few years. Here, we demonstrate the preparation of hexagonal nanoplate-like zirconium phosphate (ZrP) through a facile hydrothermal technique and its application for the electrochemical detection of furazolidone (FZD). Several characteristic measurements are systematically carried out to confirm the formation of pure-phase ZrP. The hexagonal nanoplate-like ZrP catalyst exhibits excellent electrochemical activities toward FZD detection owing to its highly active centers exposed on the surfaces and site populations. The ZrP-based sensor possesses a low limit of detection (1.2 nM), wide working range (0.009–339 μM), high sensitivity (1.312 μA/(μM cm2)), rapid response (<3 s), excellent stability, and good anti-interference ability toward FZD sensing. Furthermore, the proposed electrochemical sensor is considered competitive compared to the previously reported sensors. Besides, the practicability of the produced electrochemical sensor was successfully applied to accurately detect FZD in food samples. The synthesized nanomaterial delivers a pathway toward the rational construction of electrocatalysts for diverse electrochemical technologies.
