Abstract:

Herein, a comprehensive chemical experiment is recommended. In this experiment, CuO particles were first grown on carbon cloth via a hydrothermal reaction and then subjected to in situ transition to CuS nanosheet arrays through an anion exchange approach. The CuS product was systematically characterized and its electrochemical performance for copper storage was studied. The design of such an experiment involves the integration of chemistry, materials, energy, and other disciplines. During the experimental process, students can receive basic scientific training in nanomaterial preparation, characterization, electrode preparation, and battery assembly and testing. Such training would help to improve their understanding of materials science and the operation of experimental equipment, while enhancing critical thinking ability. In general, involvement in this experimental design would provide a solid foundation for scientific research of these students. This experiment is suggested for use as one of the comprehensive chemistry experiment courses for senior undergraduates majoring in chemistry and other related subjects.
