Zeolites for control of NOx emissions: Opportunities and challenges

Due to their unique structures and excellent properties, increasingly stringent emission legislations offer new opportunities for zeolites as commercial catalysts in emission control of nitrogen oxides (NOx) from diesel engines in heavy-duty vehicles, the preferred tools for transport of goods. New progress and ongoing challenges with regard to use of zeolites as selective catalytic reduction catalysts or passive NOx adsorbents have been concluded. The relationship between the catalytic performances with the structure, stability, and cost of the zeolites have been addressed as crucial factors for the applications of these zeolite catalysts.
