In this work, a two-dimensional leaf-like framework-L embedded electrochemically reduced graphene oxide (ERGO@ZIF-L) was proposed as an outstanding electrode material for the sensitive electrochemical sensing of benomyl (BM). ZIF-L is surrounded by ERGO, which could effectively ensure the stability and dispersion of ZIF-L. With this unique combination, the prepared ERGO@ZIF-L displayed excellent synergistic characteristics with a large surface area, excellent conductivity, plentiful active sites, and high electrocatalytic properties, thus endowing it with high sensitivity for BM determination. The experimental parameters, such as solution pH, material volume, and accumulation time, were optimized. Under optimal conditions, the BM sensor showed a wide linear range (0.009-10.0 μM) and low-limit detection (3.0 nM). Moreover, the sensor displayed excellent stability, repeatability, and reproducibility, and good anti-interference capability. The method was successfully applied to detect BM in real-world samples.

在这项工作中，提出了一种二维叶状框架-L 嵌入电化学还原氧化石墨烯（ERGO@ZIF-L），作为一种出色的电极材料，用于苯醚甲环唑（BM）的灵敏电化学传感。ZIF-L 被 ERGO 包围，这可以有效地确保 ZIF-L 的稳定性和分散性。通过这种独特的组合，制备的 ERGO@ZIF-L 具有大表面积、优异导电性、丰富的活性位点和高电催化性能等优异的协同特性，从而赋予其对 BM 测定的高灵敏度。优化了实验参数，如溶液 pH 值、材料体积和积累时间。在最佳条件下，BM 传感器表现出宽线性范围（0.009-10.0 μM）和低检测限（3.0 nM）。此外，传感器表现出优异的稳定性、重复性和重现性，以及良好的抗干扰能力。该方法成功应用于实际样品中 BM 的检测。
