NO oxidation catalysts and NO2 adsorbents based on BaO are used to remove NOx from combustion effluents that lack CO or CxHy reductants. NOx trapping materials, however, inefficiently use costly active components because of persistent ambiguities about fundamental processes responsible for NOx storage. We address such matters by combining NO oxidation and NOx adsorption rate data with infrared spectra of adsorbed species to identify elementary steps and active site requirements for NO oxidation and NOx adsorption.

Abstract
NO oxidation catalysts and NO2 adsorbents based on BaO are used to remove NOx from combustion effluents that lack CO or CxHy reductants. NOx trapping materials, however, inefficiently use costly active components because of persistent ambiguities about fundamental processes responsible for NOx storage. We address such matters by combining NO oxidation and NOx adsorption rate data with infrared spectra of adsorbed species to identify elementary steps and active site requirements for NO oxidation and NOx adsorption.File in questo prodotto:
