Reduction/oxidation half-cycles of the selective catalytic reduction of NO with NH3 (NH3–
SCR) over Fe-exchanged mordenite (MOR) zeolites at 300° C were investigated by in …

Abstract Cu-SSZ-13 (Cu-Z) has been commercialized as an efficient catalyst for NO x
removal in mobile sources. However, in practical applications, the catalyst faces problems of …

Unwanted N2O formation is a problem that has been noted in selective catalytic reduction
(SCR) where copper zeolite catalysts are utilized. With its immense global warming potential …

Cu-SSZ-13 catalysts with similar Si/Al and Cu/Al ratios were prepared by aqueous solution
ion-exchange (Cu-SSZ-13-I) and one-pot synthesis (Cu-SSZ-13-O) methods. NH3-SCR …

The mechanism of the selective catalytic reduction of NO with NH3 was studied using
Cu/SSZ-13. The adspecies of NO and NH3 as well as the active intermediates were …

In recent years, various adsorbents have been developed to alleviate atmospheric pollution
and remove harmful gases, such as carbon dioxide, sulfur dioxide, nitrogen oxides …

In order to solve the unsatisfactory NH 3-SCR in the super low-temperature range (≤ 150°
