Rh catalysts supported on knitting aryl network polymers for the hydroformylation of higher olefins

Rh catalysts supported on knitting aryl network polymers (Rh/KAPs) were prepared for the hydroformylation of higher olefins. Rh catalysts supported on triphenylphosphine-benzene-base polymers (Rh/KAPs-1) showed higher activity for the higher olefins than Rh/SiO2 catalysts. Fourier transform infrared spectroscopy, thermogravimetry, N2 adsorption-desorption, X-ray diffraction, transmission electron microscopy, 13C NMR, and 31P NMR showed that the Rh/KAPs-1 catalysts have high thermal stability, high surface area, hierarchical porosity, highly dispersed Rh nanoparticles, and in situ formed homogeneous active species during the reaction.
