Abstract

Evidence for adsorption-assisted desorption of 13NH3 in the presence of gas phase ammonia on g-alumina is presented. Due to lateral interactions with physisorbed ammonia, the adsorption enthalpy of ammonia on g-alumina was measured to be -11 kJ/mol, using a 13NH3/14NH3 isotopic exchange method. This adsorption/desorption exchange was monitored with positron emission profiling. IR spectroscopy showed ammonia to exchange preferentially on the Lewis acid sites of alumina.
