A multinuclear MAS NMR study on the stability of Ph3P-Rh/SBA-15 catalysts for hydroformylation of propylene

摘要：

Multinuclear MAS NMR together with XRD and N2 adsorption were employed to characterize the local structures of heterogeneous Ph3P-Rh/SBA-15 and supported homogeneous HRh(CO)(PPh3)3/SBA-15 catalysts. It is found that Ph3P-Rh complex can be tightly grafted on SBA-15 through the Si-O-Rh bonds while much less such bonds are formed in the supported homogeneous counterpart. This can be correlated to the longer catalytic life of heterogeneous PPh3-Rh/SBA-15 for propylene hydroformylation.
