Latest researches in catalytic mechanisms for ruthenium-based ammonia synthesis catalysts, including adsorption-dissociation of N2 over Ru surface and kinetics for ammonia synthesis catalyzed by ruthenium-based catalysts. Advances in oxides-supported ruthenium catalysts were reviewed as well, such as oxides support preparation, modification and recombination methods and the promoters. The problems with current researches in the catalytic mechanism of ruthenium-based catalysts and oxides-supported ruthenium-based catalytic system were outlined.
