Abstract

Industrially ammonia (NH₃) is produced from the energy-intensive Haber-Bosch (HB) process. Electrochemical nitrogen reduction reaction (eNRR) is often hailed as a possible alternative to the HB process, as it has lower energy requirements and can reduce N₂ to NH₃ at ambient conditions. In this review, 50 catalysts for eNRR synthesised within the last three years are judged based on the energy economics and yield rate, to determine if they could be a suitable alternative to the HB process.

氨合成的电催化剂以及我们距离哈伯-博什合成还有多远？

工业上的氨气（NH3）是由能源密集型的哈伯-博施（HB）工艺生产的。电化学氮还原反应（eNRR）通常被誉为 HB 工艺的可能替代品，因为它的能耗要求较低，并且可以在环境条件下将 N2 还原成 NH3。在本综述中，我们根据能源经济性和产率对过去三年中合成的 50 种 eNRR 催化剂进行了评判，以确定它们是否可以成为 HB 工艺的合适替代品。

期刊介绍： The development of the Current Opinion journals stemmed from the acknowledgment of the growing challenge for specialists to stay abreast of the expanding volume of information within their field. In Current Opinion in Electrochemistry, they help the reader by providing in a systematic manner: 1.The views of experts on current advances in electrochemistry in a clear and readable form. 2.Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications. In the realm of electrochemistry, the subject is divided into 12 themed sections, with each section undergoing an annual review cycle: • Bioelectrochemistry • Electrocatalysis • Electrochemical Materials and Engineering • Energy Storage: Batteries and Supercapacitors • Energy Transformation • Environmental Electrochemistry • Fundamental & Theoretical Electrochemistry • Innovative Methods in Electrochemistry • Organic & Molecular Electrochemistry • Physical & Nano-Electrochemistry • Sensors & Bio-sensors •
