摘要：
The oxidation of ammonia on a Pt/Al2O3 coated monolith has been studied under automotive NH3-slip catalyst conditions. Ammonia conversion as well as the selectivities towards the products N-2, N2O and NO are well described by a mechanistic model that is based on reaction mechanisms originally developed for NH3 oxidation in nitric acid production plants.
