- Abstract
The removal of nitrogen oxides (NOx), which are considered to play an active role in air pollution processes, is an important topic in the field of catalytic applications of ion exchanged molecular sieves. Beside other types of catalysts, like Y-Ba-Cu-oxides or Pt-coated Al2O3, copper exchanged zeolites show a high catalytic performance in the direct decomposition of NOx from emissions of diesel engines and industrial boilers. Because of their thermal stability up to 1000°C and their high activity in the oxidized state Cu2+/I+-ZSM-5 zeolites are an important alternative to common noble metal or metal oxide catalysts. A SO2-content in the feeding gas, however, which is inevitable in real exhaust gases, 'poisons' the zeolite catalyst. This behavior is also reported for Cu-MOR and Cu-FAU.
