A method of in situ formation of HRh(CO)2(PPh3)2 active species on the surface of heterogeneous Rh/SBA-15 catalyst has been developed and confirmed in this work. The amount of active species formed inside the pores can be controlled by the support pore size. This class of PPh3-Rh/SBA-15 catalyst has been employed in propene hydroformylation to be highly active, selective, stable, easily workable and recyclable. Using TEM, solid-state 31P MAS NMR, and in situ FT-IR, HRh(CO)2(PPh3)2 active species can be characterized.
