英文摘要: CO or and No co-adsorption on reduced Co/Al2O3, Mo/Al2O3 and Co-Mo/Al2O3 was studied by TPD-MS, IR and XPS. It was found that there exist two kinds of Mo-sites and three kinds of Co-sites on reduced Co-Mo/Al2O3. For Mo-sites, One is a weaker adsorption NO (T-max1 100 degrees C) which can be replaced by adsorption CO another is a stronger adsorption NO (T-max: 300 degrees C) which is not replaced by CO. Three kinds of CO-sites for NO adsorption emerged desorption peaks of NO at 80 degrees C, 180 degrees C and 330 degrees C respectively. Former two can adsorp CO however, the latter only adsorb NO and all CO adsorbed on Co-sites can be replaced by co-adsorption NO.
