Abstract:
In the present paper we review possible ways for measuring the strength of surface acid sites and for studying acid-base reactions using the proton affinity scale. PA measurements are done with the IR spectroscopy of hydrogenbonded complexes. The proton affinity of acid sites and reagent molecules is found to correlate with the heats of ions formations on the surface, and thus with the rates of catalytic reactions. Difference in the PA of acid sites and PA of bases (ΔPA=PAb-PAa) determines the threshold for the existence of H-complexes and ion pairs on the surface. Suggested is empirical method for calculating the activation energies of reactions catalyzed by the Broensted regarding the proton affinity of acid sites, bases and reaction products.
