Fig. 5: Depiction of the confinement (Kconf) and the protonation (Kprot) thermodynamic steps.
From: Understanding solvent effects on adsorption and protonation in porous catalysts
Pyridine enters the catalyst pore with an equilibrium constant of Kconf before being protonated by the BAS with an equilibrium constant of Kprot. Solid and dashed curved lines indicate zeolite pores walls and the BAS solvation sphere, respectively.
