The poisoning of sulfur oxides and alkali metals emitted from diesel exhaust to active sites copper ion-exchanged chabazite (Cu-CHA) catalysts is still present remains a formidable challenge in practical application. Herein, bifunctional core–shell structural [email protected] (Cu-SSZ-13@CZO) catalyst was designed fabricated via hydrothermally induced self-assembly protocol, the catalytic activity Cu-SSZ-13@CZO for selective reduction (SCR) nitrogen (NOx) with ammonia systematically investigated. It unveils that features Cu-SSZ-13 as core dispersed CZO shell could not only serve sacrificial site protecting SO2 by formation Ce2(SO4)3, which further act adsorption capturing K+ through strong interaction between cerium sulfate, but also render additional Brønsted acid functioning trap K+, thereafter inhibiting directly on Cu species core. As result, as-constructed catalyst, therefore, exhibits perceptibly enhanced coresistance potassium ion almost 100% NOx conversion temperature window 275–475 °C compared 350–450 pristine Cu-SSZ-13. finding here may contribute fundamental understanding metal poison inspire advancement highly efficient NH3-SCR future.

Simultaneous catalytic elimination of NO and N2O from exhausts is an ideal solution for nitric or adipic acid plants. Herein, Fe-based zeolite catalysts were applied the NH3–NOx–N2O system. 1% Fe-SSZ-13 performed excellent activity with 100% conversions both NOx at 400–600 °C. Experimental computational research studies unraveled that could significantly improve decomposition by reacting αO* to generate easily desorbed NO2; furthermore, NO−αO* also can decrease charge density Fe−αO*, facilitating Fe sites. Besides, NH3 inhibits low-temperature deN2O due strong competitive adsorption N2O; however, accelerates consuming simultaneously reduces as a reductant high temperature. Interestingly, generated would enhance oxidation NO2, which beneficial NH3-selective reduction. This work elaborates fundamental insights simultaneous abatement provides candidate catalyst application.
