Progress in Catalyst for Ammonia Synthesis

Recently,the catalysts for ammonia synthesis with higher stability,higher activity and lower cost have received considerable attention.This paper describes the new finding of the oxide-supported ruthenium catalysts for ammonia synthesis such as support preparation,catalyst reduction and the role of promoters.Advances in alloy catalysts for ammonia synthesis such as fuse iron-cobalt alloy,bimetallic nitride,as well as supported bimetallic are reviewed by combining the results of theory and experiment.The problems in the research of the oxide-supported catalysts ruthenium catalysts and alloy catalysts and the directions of the future research are also proposed.
