| 英文摘要 | co and/or no adsorption on reduced rh-2/sio2 and rh-2-v/sio2 catalysts has been studied by in situ infrared spectroscopy. the catalysts were prepared from rh-2(co)(4)cl-2 as a precursor. three kinds of rh sites are identified by co adsorption corresponding to absorbance bands at 2085, and 2028cm(-1) (rh-i(co)(2)), 2060cm(-1) ((rhco)-c-ii), 1867cm(-1) ((rh2co)-c-iii), respectively. ir bands of no adsorption of rh sites appears at 1748 and 1648cm(-1), which can be assigned to rh.no and rh-no-delta species, respectively. addition of vanadium oxide to rh-2/sio2 catalyst, decreases remarkly the number of rh-ii and rh-iii sites, and enhances the bond energy of rh-i(co)(2). the vanadium promotion is suggested as due to the electron transfer form rh-0 to vanadium ions on rh-2-v/sio2 catalyst. the results obtained from co and no adsorption on supported rh and rh-v catalysts derived from cluster and metal salt precursors, i. e.,rh-2(co)(4)cl-2 and rhcl3, have been compared. it is found that the intensity of linear adsorbed co on rh-2/sio2 catalyst is more intense than that on rh/sio2 catalyst, this indicated that more rh-0 sites were produced on rh-2/sio2 catalyst. rh-2-v/sio2 catalyst exhibits stronger electronic interaction between rh metal and vanadium ions than that on rh-v/sio2 catalyst. |
