英文摘要: Dual adsorption of NH3 and CO2 has been used to study the acid property of ZrO2 in relation to its base property by TPD and IR spectroscopy. It is found that preadsorbed NH3 (or CO2) has no inhibitory but a promotive effect to a postadsorption of CO2 (or NH3) The increased adsorption of the postadsorbed moecules is most pronounced in the TPD curves at above 510 K. In the IR observation, the dual adsorption effect is characterized by a formation, on one hand, of a monodentate carbonate species which can not be formed in the single adsorption of CO2, and by a strengthened bonding of NH3 to surface acid site (Zr4+) on the other hand. These results suggest that there exists not only independently located acid and base sites, responsible for the adsorption of NH3 and CO2, but some sites located closely(i.e acid-base pair sites). A surface induced through-bond acid-base interaction seems to be the nature of the dual adsorption effect.
