Abstract

A density functional theory study of the interaction of a Pd atom with the zeolitic Brønsted acid site is reported. Whereas reduction of Pd2+ to P and 2H+ is strongly exothermic, the energy of exchange of a single proton between P and the zeolite is found to be nearly thermodynamically neutral. Reaction energy diagrams are presented for proton-assisted CO hydrogenation and hydration.
