Abstract: This paper presents a comprehensive chemistry experiment for undergraduate laboratory teaching, derived from our research group's scientific achievements. The experiment encompasses the synthesis of graphitic carbon nitride (g-C₃N₄) and its application as a photocatalyst in the Minisci reaction between redox-active ester (NHP ester) and quinoline. Through this experiment, students gain insight into the complete scientific research process, ranging from catalyst preparation and characterization to the execution of photocatalytic reactions. The experiment incorporates fundamental laboratory techniques such as suction filtration, thin layer chromatography (TLC), and column chromatography, while also providing training in the operation of advanced instruments including a muffle furnace, gas chromatography (GC), and X-ray powder diffractometer (XRD). This experiment introduces students to the fundamental principles of photocatalysis and the concept of green chemistry, extending to the broader context of carbon peak and neutrality strategies. Furthermore, it aims to broaden students' scientific perspectives, cultivate research-oriented thinking, and enhance their interest in scientific inquiry.
