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

Abstract

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.

Electrochemical characterization of and theoretical insight into a series of 2D MOFs, [M(bipy)(C4O4)(H2O)2]·3H2O (M = Mn (1), Fe (2), Co (3) and Zn (4)), for chemical sensing applications

“…The LOD was calculated using the formula: LOD ¼ 3s/S, where s is the standard deviation of the peak current of the sensor in the blank PBS (n ¼ 5), and S is the slope of the calibration curve of NFZ. Though the LOD is not as low as other recent applications incorporating the MOF and other functional materials (Table S3 †), 17,19,21 our Mn-MOF modied electrode showed a more comprehensive linear range for the detection of NFZ. The inuence of potentially interfering substances on the determination of NFZ using the Mn-MOF modied electrode was investigated in Fig.…”
