| 英文摘要 | A series of tethered-phosphine modified Rh/SiO2 catalysts with different Rh particle size was prepared by preparation technology of shell-type catalyst, which shared the same Rh loading and P/Rh ratio. Ethylene hydroformylation was used as a probe reaction to test the performance of those catalysts. The results show that Rh particle size has a great effect on the performances of phosphine modified Rh/SiO2 catalysts. The catalytic activity increased as Rh particle size decreased, but meanwhile the induction period prolonged. The catalysts were characterized by H-2 chemical adsorption, transmission electron microscope, N-2 adsorption desorption isotherms, in situ Fourier-transform spectra and solid P-31 nuclear magnetic resonance technology. The active species were Rh-phosphine complex, and more amount of active species were produced over catalyst with smaller Rh particle size. With the decreasing of Rh particle size, the density of Rh particle on the surface decreased and it took more time for DPPPTS to reach Rh and form Rh-phosphine complex. |
