The recycling of environmental wastes to produce value‐added materials is an attractive prospect for both economic and social development. Herein, we use natural crab shell as the templates to synthesize ordered mesoporous carbon nanofiber arrays (OMCNs) based on a combined hard‐templating and surfactant self‐assembly approach. The Brunauer‐Emmett‐Teller surface area of the OMCNs is calculated to be 1200 m² g⁻¹, which is accompanied by good conductivity and a mesoporous structure. The as‐prepared OMCNs exhibit a remarkable electrochemical performance for the detection of malachite green (MG). Differential pulse voltammetry (DPV) reveals that the MG sensor has a wide linear range from 0.1 μM to 22.1 μM with a low detection limit of 0.05 μM. The MG sensor also shows a good stability and excellent anti‐interference, which are investigated by cyclic voltammetry. Furthermore, such an electrochemical sensor is successfully applied for the determination of MG in fishery water samples.

有序介孔碳纳米纤维阵列用于孔雀石绿的灵敏电化学检测

回收环境废物以生产增值材料对于经济和社会发展都是一个诱人的前景。在这里，我们使用天然蟹壳作为模板，基于硬模板和表面活性剂自组装方法，合成有序介孔碳纳米纤维阵列（OMCN）。OMCN的Brunauer-Emmett-Teller表面积经计算为1200 m ²  g ^-1，具有良好的导电性和介孔结构。所制备的OMCN在检测孔雀绿（MG）方面表现出卓越的电化学性能。差分脉冲伏安法（DPV）显示，MG传感器具有从0.1μM到22.1μM的宽线性范围，且检测限低至0.05μM。通过循环伏安法研究，MG传感器还显示出良好的稳定性和出色的抗干扰性。此外，这种电化学传感器成功地用于测定渔业水样品中的MG。
