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。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.
