The selective functionalized MCM-41-based and SBA-15-based heterogeneous catalysts were applied toward the 1-octene hydroformylation. MCM-41 materials with amine and Rh complexes in the intra-pores show a higher selectivity for linear aldehydes. The mesopore, the steric bulky triphenylphosphine ligand greatly improved the selectivity of the less hindered linear aldehydes over the branched aldehyde. It was found through in situ high pressure FT-IR study that the active species containing HRh(CO)2(PPh3)2 and HRh(CO)(Ph3P)3 were involved in the hydroformylation of 1-octene over the heterogeneous rhodium catalyst systems.
