Abstract:

Research on nitrogen-based substances, including elemental nitrogen and compounds containing a nitrogen atom, has attracted much attention, particularly for ammonia synthesis, hydrogen generation and denitration. These studies hold immense potential for applications in advancing new energy sources, mitigating environmental pollution and achieving carbon neutrality. This article introduced the concept of "N1 chemistry", highlighted several notable examples in this field, discussed significant advancements in ammonia synthesis, hydrogen generation and denitration, and presented an outlook on the future development of "N1 chemistry".

Key words: N1 chemistry, synthetic ammonia, hydrogen energy, denitration, carbon neutralization

摘要：

关于含有氮元素的单质或含有一个氮原子的化合物等相关的研究备受关注，特别是在合成氨、制氢、脱硝等方面，对于促进新能源开发，控制环境污染以及实现碳中和等具有广泛的应用前景和重要的科学意义。本文提出了“氮一化学”的理念，回顾了与“氮一化学”相关的几个典型案例，讨论了目前国内外关于合成氨、制氢、脱硝等方面的重要进展，并展望了“氮一化学”的发展前景。
