• activity; Introduction Nitrogen oxides, NOx (x = 1, 2), contribute to acid rain, photochemical smog, greenhouse effect and ozone depletion [1][2][3]. The selective catalytic reduction of NO with NH3 (SCR), as a commercialized NOx abatement technology, has received a great deal of attention [4][5]. However

• this purpose, the zeolite-mediated DeNOx-SCR (selective catalytic reduction of NOx with NH3) may serve as a model reaction, and is of great relevance in the after treatment of diesel exhaust gas as well as in NOx-emitting technical plants. It relies on the conversion of NH3 with NO/NO2 and is catalysed
