Construction of Lanthanum Vanadate/Functionalized Boron Nitride Nanocomposite: The Electrochemical Sensor for Monitoring of Furazolidone

“…The statistical analysis of the linear fitting equation of LaV/F-BN/GCE was expressed as I pc (μA) = −0.3917 [scan rate (mV/s)] – 24.631 with the R 2 of 0.995. The obtained result reveals that the electrochemical reduction of the FZD on the surface of LaV/F-BN is a process of adsorption control, similar to the previous reports. ,, …”

“…23-0324, a = 7.05 Å, b = 7.26 Å, and c = 6.75 Å). The diffraction peaks at 26.7°, 41.6°, 43.8°, 50.2°, 55.0°, 76.0°, and 82.3° were characteristics of hexagonal-BN (Figure A­(b)), which can be assigned to the (002), (100), (101), (102), (004), (110), and (112) planes, respectively . As can be seen in Figure A­(c), the peaks of LaV and F-BN were clearly noticeable, and the typical pattern for F-BN (002) was also found despite its weak diffraction intensity, indicating that the LaV/F-BN nanocomposites were successfully prepared.…”

The electrochemical performance of the LaV/F-BN modified RDGCE is measured in 0.05 M PBS (pH 7.0) at 1200 rpm.…”

“…On account of the adverse effects of FZD on human health, there is a demand to develop rapid and straightforward operations to detect it in real samples. Classically, FZD is qualified by various methods, including enzyme-linked immunosorbent assay, electrochemical sensors, liquid chromatography–tandem mass spectrometry, chemiluminescence, fluorimetry, and high-performance liquid chromatography. ,,− Electrochemical sensors have been broadly reported due to favorable aspects such as their high linear range, selectivity, operational simplicity, cost-effectiveness, sensitivity, rapid response, and trace-level detection. − Even though the traditional electrode has been identified as being capable of detection in real-world samples, the performance still suffers from fouling and selectivity. Notably, the enhanced catalytic activity of the electrochemical sensor is heavily dependent on the electrode material.…”

Design and In Situ Synthesis of Titanium Carbide/Boron Nitride Nanocomposite: Investigation of Electrocatalytic Activity for the Sulfadiazine Sensor

“…In the ultrasonication system, the TiC material was strongly exfoliated and delaminated by the direct contact with the probe horn. Encouragingly, the incorporation of TiC into other conducting material matrices exhibits superior electrocatalytic performance for the sensors. − ,− Among various conducting material matrices, hexagonal boron nitride (BN) belongs to the type of 2D materials that have a highly layered and ordered structure via the strong covalent interaction as well as the weak van der Waals bilayer interaction among the lateral adjacent B–N planes. − It consists of a large surface area, remarkable conductivity, rich chemical stability, and excellent electrical properties. These excellent properties make BN play a prominent role in endorsing the development of future electrochemical applications. − …”
