Future emission standards are becoming increasingly stringent. Around 50% of targeted
tailpipe emissions are emitted during the cold-start period, mainly due to the ineffectiveness …

It remains a major challenge to abate efficiently the harmful nitrogen oxides (NO x) in low-
temperature diesel exhausts emitted during the cold-start period of engine operation …

In this work, Pd-SSZ-13 catalysts with 1.0 wt% Pd loading were studied as passive NO x
adsorber (PNA) materials. A series of Pd-SSZ-13 catalysts were prepared by calcination of …

In this paper, Cu-exchanged SSZ-13, SAPO-18, and SAPO-34 were synthesized via a novel
green and sustainable solid-state ion-exchange (SSIE) route with excellent NH 3-SCR …

Phosphorus (P) originating from lubricant oil additives or biofuels is an emerging chemical
poison in catalytic systems for automotive exhaust after-treatment. Here, we demonstrate …

The crystal size effect on the NOx adsorption and desorption over Pd/SSZ-13 passive NOx
adsorbers (PNA) was investigated. SSZ-13 zeolites with various crystal size (0.4, 0.8, and …

Designing confined catalysis by harnessing “confinement effects”, defined as the modulated
microenvironments and physical properties that alter reaction kinetics and selectivity …

Pd/SSZ-13 samples with the same Pd loading (1 wt.%) but different Si/Al ratio (6 and 13)
were hydrothermally aged at 800, 850, and 900 ºC, respectively. The Pd/SSZ-13 with a …

The abatement of harmful nitrogen oxides (NO x) emission during vehicle cold start is
challenging. Passive NO x adsorbers (PNAs) have proven to effectively alleviate NO x …

Abstract SSZ-13 and SSZ-39, as eight-member zeolites with small pore size of∼ 0.38 nm,
show profound development potential in eliminating NOx emitted from lean-burn vehicles …
