Ammonia is one of the most important chemicals due to its enormous applications in fertilizer production and as an energy carrier. The production of ammonia mainly relies on the traditional Haber–Bosch process under high temperature and pressure, leading to massive energy consumption and notable environmental issues. Recently, electrocatalytic and photocatalytic nitrogen (N2) fixation have emerged for achieving green production of ammonia owing to their features of environmental friendliness and cost‐effectiveness. However, ammonia production through electrocatalysis and photocatalysis is still far away from practical applications. To facilitate the practical applications, a thorough understanding of nitrogen fixation is highly desired for the future design of high‐efficiency catalysts. Here, the fundamental investigations on electrocatalytic and photocatalytic N2 reduction are summarized. Based on the fundamental understanding, the current approaches and design strategies for heterogeneous catalysts toward electrocatalytic and photocatalytic N2 reduction are then presented. Finally, the remaining challenges and future opportunities in this field are outlined, leveraging the existing understanding on structure–property relationships. It is anticipated that this review sheds some light on the development of advanced catalytic systems for ammonia production through N2 fixation.

氮还原电催化剂和光催化剂设计的最新进展
氨是最重要的化学物质之一，因为它在肥料生产中具有巨大的用途，并作为能量载体。氨的生产主要依靠高温和高压下的传统Haber-Bosch工艺，导致大量能源消耗和显着的环境问题。最近，电催化和光催化氮（N 2）由于其对环境友好和成本效益高的特点，已经出现了用于实现氨绿色生产的固色剂。然而，通过电催化和光催化生产氨仍离实际应用很远。为了便于实际应用，对于未来高效催化剂的设计，非常需要对固氮有透彻的了解。在此，总结了关于电催化和光催化N 2还原的基础研究。基于基本理解，目前非均相催化剂对电催化和光催化N 2的方法和设计策略然后提出减少。最后，利用对结构-财产关系的现有理解，概述了该领域中剩余的挑战和未来的机会。可以预期，该综述为通过N 2固定生产氨的先进催化系统的发展提供了一些启示。
