Nick’s recent work, which has been accepted for publication in the Journal of Catalysis, elucidates the interaction between NaY and liquid water with in-situ ATR-FTIR spectroscopy. We show that the presence of liquid water promotes the protonation of pyridine to form pyridinium in the pores of NaY. However, the intensity of the pyridinium band is not representative of the Bronsted acid site density of NaY, as generally believed in the field, because it is largely induced by the solvent effect.
