摘要: 针对过渡金属/氧化物催化CO2加H2还原制备甲醇反应机理的碳酸盐与甲酰基路径,基于前线轨道理论,剖析了CO2加H2还原反应推测机理的合理性。建议在结构化学课程教学过程中对CO2、CO、H2等小分子的活化策略、两条路径中关键步骤的反应机理进行简单的对称性分析与介绍,这样既可以加深学生对前线轨道理论的理解,又可及时将前沿研究热点问题转化为教学素材,激发学生学习结构化学的兴趣。

Abstract: Based on the frontier orbital theory, the rationality of the reaction mechanism for both carbonate and formyl paths in the transition metal/metal oxide catalyzed CO2 hydrogenation to methanol was analyzed in detail. It is suggested that in the teaching process of structural chemistry, a simple symmetry analysis of the activation strategies of CO2, CO and H2 and the reaction mechanisms of the key steps in these two paths were conducted. This can not only deepen students' understanding of the frontier orbital theory, but also timely convert the hot research topics into teaching materials, so as to stimulate students' interest in learning structural chemistry.
