IR Characterization of Homogeneously Mixed Silica–Alumina Samples and Dealuminated Y Zeolites by Using Pyridine, CO, and Propene Probe Molecules

Homogeneously mixed silica–alumina samples with various Si/Al ratios (Si/Al = 9/1, 7/3, 5/5, 3/7, and 1/9) were prepared and characterized by infrared spectroscopy. Pyridine, propene, and CO were used as probe molecules to detect Brønsted and Lewis acid sites. The homogeneity of Si and Al in mixed o...
