“…The high potential of mesoporous zeolites is confirmed by numerous current review articles devoted to their synthesis, e.g., [1][2][3][4][5][6][7], their application in catalysis and adsorption in general [8,22,23], or in particular processes such as biomass conversion [24] or hydrocarbon oxidation reactions [25]. Despite the large amount of general scientific literature describing mesoporous zeolites, only a few reports focus on individual environmental catalysis reactions, bringing together the state of the art.…”

Mesoporous/hierarchical zeolites (HZs) are a relatively new group of materials, and interest in their application in catalysis is continuously growing. This paper presents recent achievements in the application of mesoporous zeolites in catalytic reactions of nitrogen pollutant conversion. The analysis presented includes processes such as selective catalytic reduction of NOx with ammonia (NH3-SCR, DeNOx), selective catalytic oxidation of ammonia (NH3-SCO, AMOx), and catalytic decomposition of N2O. Different zeolite topologies and methods of their modification focused on mesoporosity generation (e.g., desilication, dealumination, steaming, self-assembly techniques, and application of hard and soft templates) are reviewed and compared with respect to catalytic processes. Special attention is paid to the role of porous structure and acidity, as well as the form of deposited transition metals, in the catalytic activation of modified zeolites in the elimination of nitrogen pollutants from flue gases.
