摘要：

Ammonia is an important chemical for synthesized fertilizers traditionallyand for a potential energy vector increasingly. Industrial ammonia synthesis through theHaber-Bosch process is energy-intensive and requires advanced materials to catalyzeammonia synthesis under mild conditions, whereas the utilization of ammonia as ahydrogen carrier via ammonia decomposition is facing a similar situation as well. Thedeveloped second-generation Ru-based catalysts performs superior activities overcommercial Fe- or Ni-based catalysts; however, it remains challenging to constructeffective Ru catalysts to achieve the usage of Ru metal affordably as well as furtherunderstanding the nature of Ru catalysis. This Perspective summarizes the recentcontributions in engineering Ru-based catalysts via various strategies and related catalysisin ammonia synthesis and decomposition, and it discusses the similarities and differencesof Ru catalysis in these reactions. Finally, an overview of this area and opportunities forfurther investigation are also provided.
