Haber-Bosch工艺是固定氮的主要贡献者，支持世界的营养需求，是已知的最大规模的工业工艺之一。它也是化学家理解表面化学的试验场。因此，重要的是，用于N2还原的最彻底开发的催化剂使用钾作为电子促进剂。在这篇综述中，我们讨论了文献上的碱金属阳离子作为促进剂的N2还原，在不断增长的知识的背景下N2，过渡金属，碱金属之间的合作相互作用的配位化合物。由于这些化合物的结构和性质更容易表征，因此它们提供了关于碱金属与N2相互作用的有用信息。在这里，我们回顾了各种相互作用，重点是最近的工作，铁络合物的作者。最后，我们得出结论，这些相互作用的性质和未来的研究领域。
The Haber-Bosch process is a major contributor to fixed nitrogen that supports the world's nutritional needs and is one of the largest-scale industrial processes known. It has also served as a testing ground for chemists’ understanding of surface chemistry. Thus, it is significant that the most thoroughly developed catalysts for N2 reduction use potassium as an electronic promoter. In this review, we discuss the literature on alkali metal cations as promoters for N2 reduction, in the context of the growing knowledge about cooperative interactions between N2, transition metals, and alkali metals in coordination compounds. Because the structures and properties are easier to characterize in these compounds, they give useful information on alkali metal interactions with N2. Here, we review a variety of interactions, with emphasis on recent work on iron complexes by the authors. Finally, we draw conclusions about the nature of these interactions and areas for future research.
