摘要:
The abatement of harmful nitrogen oxides (NOx) emission during vehicle cold start is challenging. Passive NOx adsorbers (PNAs) have proven to effectively alleviate NOx emission at low temperatures. In this work, Pd-based Na-SSZ-13 (Pd/Na-13) was synthesized and hydrothermally aged to investigate the effect of Na co-cations on the structure and activity of Pd/SSZ-13 for low-temperature NO adsorption. Compared to Pd-based NH4-SSZ-13 (Pd/NH4-13), Pd/Na-13 exhibited superior stability and activity promoted by Na co-cations in SSZ-13. DRIFTS and 27A...
