Zeolites with ordered microporous systems, distinct framework topologies, good spatial
nanoconfinement effects, and superior (hydro) thermal stability are an ideal scaffold for …

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 …

The performance of Cu-chabazite (Cu-CHA) zeolite, the state-of-art catalyst for the ammonia-
assisted selective reduction (NH 3-SCR) of toxic NO x pollutants from heavy-duty diesel …

As a new type of catalyst with the potential for commercial application in NO x removal from
diesel engine exhausts, Cu-SSZ-39 catalysts must have excellent resistance to complex and …

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 …

Despite of the main techniques like Passive NO x adsorbents (PNAs), NO x Storage and
Reduction (NSR), and Selective Catalytic Reduction (SCR), newly coupling technologies …

Optimizing metal catalyst structures to achieve desired states is vital for efficient surface
reactions, yet remains challenging due to the lack of well-defined precursor materials and …

The design of novel functional nanostructures for advanced chemical engineering field is of
great importance. In this work, Pd-modified Na-doped WO 3 nanorods are rationally …

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 …

Passive NO x adsorption (PNA) is a novel technology to control NO x emissions during cold
start. However, the recent generation of PNA material, Pd/zeolite, suffers from major …
