Vehicular pollution has become a major problem in urban areas due to the exponential rise
in the number of automobiles. Typical exhaust emissions which include nitrogen oxides (NO …

This paper gives a critical overview of the recent advances in NOx abatement in excess of
oxygen based on the combination of the NOx storage–reduction (NSR) and selective …

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 …

Pt-and Pd-promoted Ce x Zr1–x O2 mixed oxides were characterized and investigated for
passive NOx adsorber applications. X-ray diffraction analysis revealed a phase transition …

CeO 2 promoted with either 1 wt% Pt or 1 wt% Pd was evaluated as a model system for
passive NO x adsorber applications. According to NO x storage experiments conducted over …

The effect of ceria and ceria–zirconia modification to alumina on the three-way catalytic
(TWC) performance of alumina supported Pt catalyst was investigated. Sintering of Pt was …

At present, passive NOx adsorbers (PNAs) represent one of the most effective technologies
for addressing NOx emissions from diesel engines during cold-start periods. Conventional …

The role of La doping with different content in the structure of Ce0. 2Zr0. 8O2 solid solution
(CZ) and the effect of modification on the catalytic activity of supported Pd-only three-way …

Three kinds of model ceria-containing LNT catalysts, corresponding to Pt/Ba/CeO2,
Pt/CeO2/Al2O3 and Pt/BaO/CeO2/Al2O3, were prepared for comparison with a standard …

Herein, the adsorption behaviors and interactions of different gas species on single-metal
atom-anchored graphenylene (M–graphenylene, M= Mn, Co, Ni, and Cu) sheets were …
