Abstract: Ammonia synthesis process has a great impact on food production, energy security and environmental protection. The industrial ammonia synthesis based on the Haber-Bosch process, however, is an energy consuming and high emission process. Increasing efforts have been devoted to the development of new technologies and processes for "green" ammonia synthesis driven by renewable energies under mild conditions. In recent years, encouraging progresses have been made in the fields of heterogeneous catalysis, chemical looping, electro-and photo-chemical ammonia production, with significant advancements in fundamental understanding and breakthroughs. In this paper, the research status and challenges in this field are analyzed, and the recent achievements are highlighted.

Key words: ammonia synthesis, heterogeneous catalysis, chemical looping, electro-catalysis, photo-catalysis
