“…Molecules 2023, 28, x FOR PEER REVIEW 8 of 14 performance of MXene@Co/NC/GCE was further compared with previously reported electrochemical CBZ sensors (shown in Table 1). The results showed that the MXene@Co/NC/GCE possessed a wider linear range and lower LOD than the other sensors, including graphene-based sensing platforms [12,38], carbon nanotube-based sensing platforms [39,40], AuNPs/BC/GCE [41], and In2S3/GCE [42], which might be attributed to the synergetic effect between the large surface area, excellent catalytic performance, and rapid electronic transfer of MXene@Co/NC.…”

Herein, ZIF-67-derived Co and N-doped carbon (Co/NC) particle-modified multilayer MXene (MXene@Co/NC) was developed as remarkable electrode material for carbendazim (CBZ) detection. MXene as a substrate provides an excellent conductive framework and plentiful accessibility sites. Co/NC particles embedding in MXene can not only prevent the interlayer stacking of MXene but also contribute a great deal of metal catalytic active sites and finally improve the adsorption and catalytic properties of the composite. Accordingly, the MXene@Co/NC electrode displays excellent electrocatalytic activity toward CBZ oxidation. Experimental parameters such as pH value, accumulation time, MXene@Co/NC modification volume and constituent materials’ mass ratios were optimized. Under optimal conditions, the as-prepared sensor based on MXene@Co/NC holds a broad linearity range from 0.01 μM to 45.0 μM with a low limit of detection (LOD) of 3.3 nM (S/N = 3, S means the detection signal, while N represents the noise of the instrument). Moreover, the proposed sensor displays excellent anti-interference ability, superior reproducibility, excellent stability, and successfully achieves actual applications for CBZ detection in a lettuce sample.

“…As one of the most widely applied benzimidazole fungicides, carbendazim shows broad-spectrum preventive and therapeutic effects on plant pathogens and has long been adopted to address fungal diseases, which cause serious losses in agriculture and forestry. The structure of the benzimidazole ring endows carbendazim with high stability, causing long-term protection but a low degradation rate . Residual carbendazim can accumulate in both humans and animals through food chains and further cause risks such as teratogenicity, infertility, and hepatocellular dysfunction .…”

This study introduces an easy and efficient ultrasonic-assisted approach for the preparation of mesoporous praseodymium cerate (MS-Pr2Ce2O7) by employing maltose as a novel and eco-friendly capping agent. Some techniques such as field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD) were used for the characterization of nanoparticles. For the detection of carbendazim (CBZ), a new electrochemical sensor based on the modified screen-printed electrode (SPE) has been presented. The modification of the electrode surface was made using of praseodymium cerate. Cyclic voltammetry (CV) has been utilized to study the electrochemical behavior of the MS-Pr2Ce2O7/SPE and better electrochemical performance was observed compared to bare SPE for the oxidation of CBZ. The optimization of pH and accumulation time was done. Under optimized conditions (pH=7 and accumulation time:160 s), the oxidation peak currents that responded to CBZ concentration between 0.01 and 175.0 µM exhibited a linear relationship (R2 = 0.9977) and the detection limit was calculated 4.6 nM. In addition, MS-Pr2Ce2O7/SPE showed high stability and repeatability. At last, real sample tests of the MS-Pr2Ce2O7/SPE were validated by applying them to the detection of CBZ in vegetable samples, which were found to be promising in our preliminary experiments.
