[1E07] Development of Ni-Ir alloy catalyst for hydrogenation of unsaturated compounds

○Masazumi Tamura¹ (1. Osaka City University)

Hydrogenation of unsaturated compounds is one of the important reactions in organic synthesis, and the development of effective heterogeneous catalysts is always required. We found that SiO₂-supported Ni-Ir alloy was an effective heterogeneous catalyst for hydrogenation of styrene, showing 7-fold higher activity based on the catalyst amount than the monometallic counterpart catalysts such as Ni/SiO₂ and Ir/SiO₂. Moreover, the catalyst was applicable to the hydrogenation of various styrene derivatives and linear olefins, and also showed higher activity for hydrogenation of pyridine.
