Although the present university-level chemistry experimental curriculum has been extensive and well-designed, it lacks a connection with the scientific research field, especially the frontier field. It is crucial to incorporate recent discoveries through new experiment designs to bridge this gap and boost the value of the undergraduate experimental course. Under the background of advancing with the times, this paper integrates the scientific research results of electrocatalytic ammonia synthesis (through nitrogen reduction reaction, NRR) into the undergraduate teaching classes, which is conducive to improving students’ scientific analysis ability and their green environmental awareness. Two lead dioxide catalysts with different crystal phases were prepared on a carbon cloth substrate by a simple water bath method. The structure, composition, and morphology of the two catalysts were characterized, and the electrocatalytic ammonia synthesis performance of the two catalysts was explored. This experimental project not only covers the teaching content of inorganic, analytical, and physical chemistry but also cultivates students’ basic experimental operation skills and the ability to use modern instruments to analyze the structure of materials, stimulate students’ interest in learning, and improve students’ scientific research literacy.

二氧化铅的合成及其氨合成电催化性能评价

目前大学化学实验课程虽然内容丰富、设计完善，但缺乏与科研领域特别是前沿领域的联系。通过新的实验设计整合最新的发现来弥补这一差距并提高本科生实验课程的价值至关重要。在与时俱进的背景下，本文将电催化合成氨（通过氮还原反应，NRR）的科研成果融入到本科教学课堂中，有利于提高学生的科学分析能力和绿色环保意识。采用简单的水浴法在碳布基底上制备了两种不同晶相的二氧化铅催化剂。对两种催化剂的结构、组成和形貌进行了表征，并探讨了两种催化剂的电催化氨合成性能。本实验项目不仅涵盖了无机化学、分析化学、物理化学的教学内容，还培养了学生基本的实验操作技能和利用现代仪器分析材料结构的能力，激发学生的学习兴趣，提高学生的综合素质。 '科研素养。
