Unrestrained anthropogenic activities have severely disrupted the global natural nitrogen cycle, causing numerous energy and environmental issues. Electrocatalytic nitrogen transformation is a feasible and promising strategy for achieving a sustainable nitrogen economy. Synergistically combining multiple nitrogen reactions can realize efficient renewable energy storage and conversion, restore the global nitrogen balance, and remediate environmental crises. Here, we provide a unique aspect to discuss the intriguing nitrogen electrochemistry by linking three essential nitrogen-containing compounds (i.e., N , NH , and NO ) and integrating four essential electrochemical reactions, i.e., the nitrogen reduction reaction (N RR), nitrogen oxidation reaction (N OR), nitrate reduction reaction (NO RR), and ammonia oxidation reaction (NH OR). This minireview also summarizes the acquired knowledge of rational catalyst design and underlying reaction mechanisms for these interlinked nitrogen reactions. We further underscore the associated clean energy technologies and a sustainable nitrogen-based economy.
无节制的人为活动严重扰乱了全球自然氮循环，导致了许多能源和环境问题。电催化氮转化是实现可持续氮经济的一种可行且有前景的策略。协同结合多种氮反应可以实现高效可再生能源存储和转换，恢复全球氮平衡，并修复环境危机。在这里，我们通过将三种基本含氮化合物（即 N 2 、NH 3 和 NO 3 - ）和整合四种基本电化学反应（即氮还原反应（NRR）、氮氧化反应（NOR）、硝酸盐还原反应（NO 3 - RR）和氨氧化反应（NH 3 OR））联系起来，提供了一个独特的角度来讨论有趣的氮电化学。本文还总结了这些相互关联的氮反应中合理的催化剂设计和潜在反应机制的已有知识。我们进一步强调了相关的清洁能源技术和基于氮的可持续经济。
