摘要：

Herein, the influence of phosphorus poisoning on the catalytic performance of Cu/SSZ-13 zeolite catalysts for NOx emission decrease was studied. We conducted a detailed analysis of catalyst activity and N-2 selectivity in both fresh and P-poisoned states, employing a range of advanced physicochemical characterization methods and in situ analyses. Our findings reveal a dual effect of phosphorus addition: Although it decreases the free Cu2+ species and specific surface area, leading to diminished SCR activity at low temperatures, it simultaneously reduces CuOx content, inhibiting nonselective NH3 oxidation at high temperatures and ultimately enhancing SCR activity under those conditions. These insights highlight the complex role of phosphorus in moderating catalyst behavior.
