英文摘要	The forms of adsorption sites, dynamic behavior of chemisorbed CO and CO disproportionation have been investigated by using CO and NO as double probes and TP - IR dynamic method. The results indicate that there are a large amount of adsorption sites for gem dicarbonyl CO and a very small amount of adsorption sites for linear CO on Rh, and Co sites for adsorbed NO over Rh + Co/Al2O3. The bands of gem - dicarbonyl CO gradually decreased in intensity and fully desorbed at 300 degrees C during TPD(in vacuum) dynamic process. The temperature fully desorbed for gem - dicarbonyl CO on Rh + Co/Al2O3 is lower than that for gem - dicarbonyl CO on Rh-4/Al2O3 indicating that addition of Co weaken CO adsorption strength on Rh-I sites over Rh + Co/Al2O3. The results obtained from TP (in CO) dynamic process indicate that CO disproportionation take place above 250 degrees C and the rate of CO disproportionation on Rh-I sites is higher than that on linear sites CO over Rh + Co/Al2O3.
