The activation of dinitrogen as a fundamental step in reactions to produce nitrogen compounds, including ammonia and nitrates, has a cornerstone role in chemistry. Bringing together research from disparate fields where this can be achieved sustainably, this seeks to build connections between approaches that can stimulate further advances. In this paper we set out to provide an overview of these different approaches and their commonalities. We explore experimental aspects including the positive role of increasing nitrogen pressure in some fields, as well as offering perspectives on when N experiments might, and might not, be necessary. Deconstructing the nitrogen reduction reaction, we attempt to provide a common framework of energetic scales within which all of the different approaches and their components can be understood. On sustainability, we argue that although green ammonia produced from a green-H-fed Haber-Bosch process seems to fit the bill, there remain many real-world contexts in which other, sustainable, approaches to this vital reaction are urgently needed.
将氮气活化作为生产氮化合物（包括氨和硝酸盐）反应中的一个基本步骤，在化学领域具有基石性作用。本文汇集了来自不同领域的研究成果，这些研究能够以可持续的方式实现氮气活化，旨在建立起能推动进一步发展的方法之间的联系。在本文中，我们着手概述这些不同的方法及其共性。我们探讨了实验方面的内容，包括在某些领域提高氮气压力的积极作用，以及对何时可能需要以及何时可能不需要进行氮实验提供观点。通过解构氮还原反应，我们试图提供一个能量尺度的通用框架，在这个框架内可以理解所有不同的方法及其组成部分。关于可持续性，我们认为，尽管通过绿色氢源哈伯-博施法生产的绿色氨似乎符合要求，但在许多实际情况下，迫切需要其他可持续的方法来实现这一至关重要的反应。
