In the present study, we report a facile method for preparing a porous MWCNTs/ZIF‐67 nanocomposite with the help of a morphology‐maintained ZIF‐67 in situ growth on multi‐walled carbon nanotubes. Interesting, the MWCNTs/ZIF‐67 nanocomposite demonstrated excellent electrochemical activity for hydroquinone (HQ) and catechol (CC) attribute to the effective interconnections ZIF‐67 crystals and MWCNTs. The analytical curves for HQ and CC obtained by differential pulse voltammetry (DPV) were linear in the range from 0.5 to 100 μM. Benefitting from the excellent conductivity of MWCNTs as well as the high surface area and porosity of ZIF‐67, the advanced nanocomposite displayed good reproducibility, high selectivity and excellent stability, and was successfully employed to assay the content of dihydroxybenzene isomers in the lake water samples.

在多壁碳纳米管上原位生长钴基金属有机骨架，用于同时检测对苯二酚和邻苯二酚。

在本研究中，我们报告了一种借助形态保持的ZIF-67原位制备多孔MWCNTs / ZIF-67纳米复合材料的简便方法在多壁碳纳米管上生长。有趣的是，MWCNTs / ZIF-67纳米复合材料表现出对苯二酚（HQ）和邻苯二酚（CC）优异的电化学活性，这归因于ZIF-67晶体和MWCNT的有效互连。通过差分脉冲伏安法（DPV）获得的HQ和CC的分析曲线在0.5至100μM范围内呈线性关系。得益于MWCNTs优异的电导率以及ZIF-67的高表面积和孔隙率，这种先进的纳米复合材料具有良好的重现性，高选择性和出色的稳定性，并成功地用于测定湖水样品中二羟基苯异构体的含量。 。
