Abstract In order to meet the requirements of engineering certification education for the cultivation of students' practical ability, a comprehensive experiment of “rapid synthesis and electrochemical performance of NMV polyoxometalates(POMs) under alcohol reagent” was designed in the experiment of energy and chemical engineering specialty. The experimental contents include the rapid synthesis, structural characterization and electrochemical performance test of NMV POMs. Students are required to understand the synthesis process and conditions of NMV POMs through literature review, design the synthesis scheme of NMV POMs, master the characterization methods such as X-ray diffraction, X-ray single crystal diffraction, thermogravimetry and the electrochemical performance test methods of NMV, and analyze and summarize the experimental data. In addition, an assessment system that takes into account both the process and the results is established to comprehensively examine the students' comprehensive practical ability through the links of experimental scheme design, experimental process operation and experimental report writing. The experimental teaching design reflects the dominant position of students. Through this teaching practice, students' practical ability, thinking ability and practical ability are not only improved, but also their innovative thinking is cultivated.
