作为一种有前景的能源载体，电催化氮还原反应（eNRR）合成氨是一种有前景的绿色低碳氨合成策略，可以替代传统的Haber-Bosch工艺。然而，eNRR工艺的发展主要受到竞争性析氢反应（HER）的严重制约，而抑制这种不良副反应以获得高eNRR选择性的相应策略仍然有限。此外，对于这种涉及气-液-固三相界面和质子/电子传递的复杂反应，从动力学角度分析和总结现有的抑制HER策略具有重要意义。鉴于此，本工作回顾了催化系统中的质子供应/过滤调节策略，对界面膜调节（无机膜和有机膜）、电解质调节（金属介导策略和电解质离子调节策略）的文献进行了系统的综述）和系统装置设计（电极结构设计和电解槽装置设计）。还提出了建设性催化系统设计指导，以抑制析氢并提高 NH ₃选择性，旨在实现可扩展且经济可行的应用。

Interfacial Proton Supply/Filtration Regulates the Dynamics of Electrocatalytic Nitrogen Reduction Reaction: A Perspective

As a promising energy carrier, ammonia synthesis by electrocatalytic nitrogen reduction reaction (eNRR) is a promising green and low-carbon ammonia synthesis strategy that can replace the traditional Haber–Bosch process. However, the development of eNRR processes is mainly severely constrained by competitive hydrogen evolution reaction (HER), and the corresponding strategies to inhibit this adverse side reaction to obtain high eNRR selectivity are still limited. In addition, for this complex reaction involving gas–liquid–solid three-phase interface and proton/electron transfer, it is great significance to analyze and summarize the existing inhibition HER strategies from the viewpoint of dynamics. In view of this, this work reviews proton supply/filtration regulation strategy in catalytic system, allowing a systematic survey of the literature focusing on interface membrane regulation (inorganic membrane and organic membrane), electrolyte regulation (metal-mediated strategy and electrolyte ion regulation strategy) and system device design (electrode structure design and electrolytic cell device design). Constructive catalytic system design guidance is also suggested to inhibit hydrogen evolution and improve NH₃ selectivity, aiming for scalable and economically feasible applications.
