摘要: 介绍了一个由科研成果转化的大学综合化学实验，本综合实验以ZIF-67金属有机框架材料为基础，以制备高灵敏叔丁基对苯二酚电化学检测传感器为目标。常温条件下溶液合成ZIF-67金属有机框架材料，还原气氛热解得到Co纳米颗粒和氮掺杂碳纳米管(Co/NCNTs)复合材料，以此材料修饰玻碳电极，考察其检测食用油中常用抗氧化剂成分叔丁基对苯二酚的能力。制备的材料由扫描电子显微镜(SEM)、X射线衍射仪(XRD)、透射电子显微镜(TEM)和能量色散X射线光谱仪(EDX)表征形貌、结构和元素组成。实验所用试剂易得，操作简单，成功率高；从材料制备、结构表征到性能测试对学生进行完整的科研操作训练，使其熟悉金属有机框架材料的概念，了解材料构性关系，不仅有利于提高学生的综合实验能力，也可以培养学生的科研兴趣，拓展学生的视野。

Abstract: This paper presents a comprehensive chemistry experiment that translates a research result into undergraduate laboratory teaching. The experiment focuses on the synthesis of a highly sensitive electrochemical sensor for tert-butylhydroquinone (TBHQ) using ZIF-67 metal-organic framework (MOF) materials as a foundation. ZIF-67 MOF material was synthesized in solution at room temperature, followed by the preparation of Co nanoparticles and nitrogen-doped carbon nanotubes (Co/NCNTs) composite material through reduction atmosphere pyrolysis. The glass-carbon electrode was then modified with this material to investigate its detection capability for TBHQ, a common antioxidant component in edible oil. The morphology, structure, and elemental composition of the prepared materials were characterized using Scanning Electron Microscope (SEM), X-ray diffraction (XRD), Transmission Electron Microscope (TEM) and Energy Dispersive X-Ray Spectrometer (EDX). This experiment offers readily available reagents, simple operation, and a high success rate, providing students with comprehensive training in scientific research procedures, familiarity with the concept of metal-organic framework materials, and an understanding of structure-property relationships. It not only enhances students’ comprehensive laboratory skills but also cultivates their interest in scientific research and expands their perspectives.
