Metal-Organic Framework-Derived Materials Modified Electrode for Electrochemical Sensing of Tert-Butylhydroquinone:A Recommended Comprehensive Chemistry Experiment for Translating Research Results
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.
