摘要： 对标“101计划”化学测量学教学改革要求，设计和开发了一项基于电化学原位拉曼光谱技术的创新仪器分析实验。主要基于电催化硝酸根还原合成氨这一绿色合成工艺，借助先进的电化学原位拉曼光谱技术实时追踪催化剂表面活性位点与关键中间体的动态演变，以准确鉴定真实的催化活性位点，推断可能的反应路径。本实验构建了完整的“反应-表征-机理”一体化的实验教学体系，聚焦于帮助学生掌握知识、提升能力以及全面培育素养。并且，充分展现出前沿科学对先进表征技术的依赖和需求，填补了“原位表征-电催化反应”交叉课程的空白，可作为“科研-教学双螺旋驱动”模式下新工科实验教学改革的典型范例。

Abstract: Aligned with the “101 Plan” teaching reform objectives for chemical measurement experiments, an innovative instrumental analysis experiment utilizing electrochemical in situRaman spectroscopy was designed and developed. Based on the green ammonia synthesis from electrocatalytic nitrate reduction, this study aims to track the real-time dynamic evolution of active sites and key intermediates on the catalyst surface through the advanced in situ Raman spectroscopy technology, to accurately identify the true catalytic active sites and infer the possible reaction pathways. This experiment has established a comprehensive experimental teaching system that integrates “reaction-characterization-mechanism”, focusing on helping students master knowledge, enhance abilities, and cultivate comprehensive qualities. This experiment fully demonstrates frontier science’s reliance and need for advanced characterization techniques, filling the gap in the interdisciplinary course of “in situ characterization-electrocatalytic reaction”. It can serve as a typical example of experimental teaching reform in new engineering disciplines under the “double helix of scientific research and teaching” model.
