Evidence for adsorption assisted desorption of 13NH3 in the presence of gas phase ammonia on γ-alumina is presented. Due to lateral interactions with physisorbed ammonia, the adsorption enthalpy of ammonia on γ-alumina was measured to be −11 ± 1

The low-temperature deactivation of a platinum sponge catalyst used for ammonia oxidation was studied with the positron emission profiling technique (PEP). Evidence that irreversibly adsorbed nitrogen species deactivate the catalyst is presented. Two

Positron emission profiling (PEP) is applied to study the adsorption and dissociation of ammonia on metallic and preoxidized platinum sponge in the temperature range 323–573 K. The results show that ammonia weakly interacts with platinum without di

Deactivation of a Pt/γ-alumina catalyst used for low-temperature ammonia oxidation was studied using positron-emission profiling (PEP). Evidence is presented that irreversibly adsorbed nitrogen and oxygen species deactivate the catalyst. This deacti

A fast and reproducible production method for pure gaseous [13N]NH3 pulses has been developed. 13N was produced by irradiation of water with 500 nA of 16 MeV protons via the 16O(p,α)13N reaction. A mixture of DeVarda's alloy and NaOH was used to con
