Shrnutí:We report measurements in copper mordenites showing that silica-alumina molar ratio (MR) strongly affects conversion efficiency for NOx, and that these catalysts are among the most active available for de-NOx at moderate temperatures. Copper mordenites' rapid deactivation by water has led us to also investigate the effects of adsorbed water on framework and extra-framework ions, mainly using NMR of 27Al and 1H. Ad-sorbed water content has been monitored and controlled in mordenite samples via TGA, as well as by vacuum calcination. Several proton NMR measurements have been performed to aid in the interpretation of spectra, including variable pulse-delay spin echo and 1H/ 27Al TRAPDOR. A number of surface characterization techniques have been applied to both H and Cu mordenites.
