| 英文摘要 | the temperature-programmed desorption (tpd) was employed to investigate the adsorption-desorption behavior of co, h-2 and c2h4 on the rh/sio2 catalyst modified with pph3 ligand (pph3-rh/sio2). the result showed that there were three co desorption peaks at 348, 398 and 525 k on rh/sio2, while only one co desorption peak at 368 k was observed on pph3-rh/sio2. analogously, only one desorption peak of h-2 and c2h4 appeared on pph3-rh/sio2. these results implied that the adsorption-desorption behavior of co, h-2 and c2h4 on pph3-rh/sio2 was different from that on rh/sio2. the adsorption states of co on pph3-rh/sio2 were studied using in situ ft-ir technique. the result revealed that the ir absorption peak at 2 040 cm(-1), corresponding to the co-tpd desorption peak at 368 k on pph3-rh/sio2, was assigned to the linear co state on the surface pph3-modified rh particles. this adsorption-desorption behavior of co on pph3-rh/sio2 was not only different from that of rh/sio2, but also distinguished from that of carbonyl on homogeneous catalysts. the tpd and ft-ir results indicated that the pph3-rh/sio2 had catalytic performance for hydroformylation at lower pressure. |
