The selective catalytic reduction of NOx with ammonia (NH3–SCR) has been studied over Cu–CHA catalysts in which the loading of copper species was achieved using three different synthetic routes: two are based on post-synthetic treatment of the zeolite material (via aqueous or vapor phase) and a third involves the direct synthesis of a Cu-loaded SAPO-34. The catalysts were subsequently characterized by XRD, solid-state NMR, UV–vis and XAFS spectroscopies. Whilst the catalysts prepared via wet… CONTINUE READING
