Hydrogenation of olefins over hydrido chlorocarbonyl tris-(triphenylphosphine) ruthenium(II) complex immobilized on functionalized MCM-41 and SBA-15

Hydrido chlorocarbonyl tris-(triphenylphosphine) ruthenium(II) complex [RuHCl(CO)(PPh3)(3)] has been immobilized inside the pores of an-tine 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.
