| Research Abstract |
Relationship between the structure and acid strength of zeolite was analyzed by means of combined ammonia IRMS-TPD (infrared/mass spectroscopic temperature-programmed desorption) measurements and DFT (density functional theory) alculations. Compression from the both sides of AlOHSi unit due to the framework topology makes the AlO distance hort, resulting in withdrawing the electron of OH by Lewis acidic Al and strong acidity of OH. In addition, it is ow possible to predict the acid strength of unknown zeolite.
