Abstract
Mesostructured cellular foams (MCF) were used as supports in developing a PPh3-Rh/MCF catalyst as a practical application for these materials. The turnover frequency of butyraldehyde, conversion of propylene, and regioselectivity for butyraldehyde over PPh3-Rh/MCF were comparable to those over the immobilized homogeneous catalyst (HRh(CO)(PPh3)3/MCF) when there was 80% exposure of the rhodium metal. The (PPh3)3/MCF) catalyst showed a far higher activity and selectivity than the classical heterogeneous Rh/MCF catalyst. The HRh(CO)(PPh3)3/MCF catalyst reached its highest activity at about 10 hr, and then decreased rapidly. The stability of the PPh3-Rh/MCF catalyst was maintained for about 250 hr.
