| 英文摘要 | the effect of h-2 on the adsorption and desorption behavior of co on the rh-mn-li-ti/sio2 catalyst was examined by ir spectroscopy and temperature-programmed desorption. the results indicated that the pre-adsorbed h-2 mainly occupied the adsorption sites for linearly adsorbed co, and the part of subsequently adsorbed co reacted with adsorbed hydrogen producing carbonyl hydrides. in the mixture of co and hydrogen, carbonyl hydrides were also formed on rh sites causing the red shift of the ir band of linearly adsorbed co, and the high hydrogen concentration enhanced the co adsorption. at 323 k, the ir band position and intensity of pre-adsorbed co were not sensitive to the hydrogen. however, with increasing temperature, the presence of hydrogen promoted the desorption of weakly adsorbed co, and its re-adsorption, as well as the dissociation of strongly adsorbed co. in addition, the existence of hydrogen intensified the co adsorption and influenced the structure of rh giving rise to the increase in rh dispersion and thereby the amount of co adsorbed on rh at 323 k. |
