Based on the activation energy of the reaction occurring at the electrode, the structure of the glassy carbon electrode (GCE) surface changes before and after pre-anodization and hydrogen bonding catalysis. This causes differences in the voltammograms of acetaminophen measured before and after pre-anodization using a GCE. These differences are discussed in this paper by applying the inquiry teaching mode, whicn can not only improve the quality of delivering chemistry experiments but also the teachers’ instructional skills.
