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.
