As an important chemical product and carbon-free energy carrier, ammonia has a wide range of daily applications in several related fields. Although the industrial synthesis method using the Haber-Bosch process could meet production demands, its huge energy consumption and gas emission limit its long-time development. Therefore, the clean and sustainable electrocatalytic N reduction reaction (NRR) operating under conditions have attracted great attention in recent years. However, the chemical inertness of N molecules makes it difficult for this reaction to proceed. Therefore, rationally designed catalysts need to be introduced to activate N molecules. Here, we summarize the recent progress in low-dimensional nanocatalyst development, including the relationship between the structure and NRR performance from both the theoretical and experimental perspectives. Some insights into the development of NRR electrocatalysts from electronic control aspects are provided. In addition, the theoretical mechanisms, reaction pathways and credibility studies of the NRR are discussed. Some challenges and future prospects of the NRR are also pointed out.
作为一种重要的化工产品和无碳能源载体，氨在多个相关领域有着广泛的日常应用。尽管采用哈伯-博施法的工业合成方法能够满足生产需求，但其巨大的能源消耗和气体排放限制了其长期发展。因此，近年来在温和条件下运行的清洁可持续电催化氮还原反应（NRR）引起了极大关注。然而，氮分子的化学惰性使得该反应难以进行。因此，需要引入合理设计的催化剂来活化氮分子。在此，我们总结了低维纳米催化剂开发的最新进展，包括从理论和实验角度探讨结构与NRR性能之间的关系。从电子调控方面对NRR电催化剂的发展提供了一些见解。此外，还讨论了NRR的理论机理、反应途径和可信度研究。同时也指出了NRR面临的一些挑战和未来前景。
