Hydrido chlorocarbonyl tris-(triphenylphosphine) ruthenium(II) complex immobilized inside the pores of amine functionalized MCM-41 and SBA-15 materials were highly active in liquid phase hydrogenation of olefins than the neat complex catalyst. The catalyst immobilized in SBA-15 showed higher activity than MCM-41 in hydrogenation reaction. Hydrido chlorocarbonyl tris-(triphenylphosphine) ruthenium(II) complex [RuHCl(CO)(PPh 3) 3] has been immobilized inside the pores of amine functionalized MCM-41 and SBA-15 materials. These grafted complexes were characterized by XRD, FTIR, N 2 adsorption measurements, XPS and tested as catalyst for the hydrogenation of olefins. Immobilization and pore size has marked effects on the catalytic activity in the hydrogenation of olefins and the complex immobilized on functionalized SBA-15 was found to be catalytically more active than the one immobilized on MCM-41.
