Dr. Olivier Cairon Impacts of Composition and Post-Treatment on the Brønsted Acidity of Steam-Treated Faujasite: Insights from FTIR Spectroscopy ChemPhysChem 14
The acid test: The effects of steaming and acid leaching on protonated Y faujasite and EMT zeolites are studied by FTIR spectroscopy. Brønsted acidic evolution and strength measurements are performed for a series of modified zeolites using CO as a probe. A correlation combining Δν(OH), ν(CO) position and Hammett H0 values is proposed together with Si/framework Al (AlF) dependence for structural IR high-frequency (HF)OH groups (see picture).
