摘要：

以水热法在碳布上生长CuO颗粒，然后通过阴离子交换转化为CuS纳米阵列，对该纳米阵列进行理化性质表征及电化学储铜研究。一系列实验涉及化学、材料和能源等多学科交叉，各学科的实用性、新颖性在其中充分融合贯通。在纳米材料制备、材料表征、电极制备、电池组装和电化学性能测试等实验过程中，学生可以得到基本的科研训练，有助于提升理论知识的理解能力、实验设备的操作能力以及科研探索和创新能力，同时激发科研兴趣并为下一步的科研工作打下坚实基础。本实验可以作为化学及相关专业高年级本科生的综合化学实验课程内容之一。

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.
