Selective catalytic reduction (SCR) using zeolite catalysts is a key technology for the
abatement of nitrogen oxides (NO x) from lean-burn heavy-duty vehicles. With the increasing …

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 …

Recently, NO x emissions in the cold-start period have been a great challenge in eliminating
diesel vehicle exhaust. In this study, a type of NO x adsorption-selective catalytic reduction …

The latest generation of heavy-duty vehicles (Euro VI step E) have to respect low emission
limits both in the laboratory and on the road. The most challenging pollutants for diesel …

Reducing diesel engine emissions under cold start conditions has become much more
valuable as environmental issues become more important. Regarding diesel engine …

A new dual layer monolithic AdSCR system (adsorption+ selective catalytic reduction)
constituted by Cu/CHA (top) and BaO/Al 2 O 3 (bottom) was prepared and studied as a …

Selective catalytic reduction of NO x by NH3 (NH3-SCR) for diesel emission control at low
temperatures is still a great challenge due to the limit of the urea injection threshold and …

Low-temperature NO decomposition with high efficiency and low energy consumption
remains a huge challenge. Herein, we reported a novel adsorption–microwave catalytic …

In response to the issue of hydrocarbon emissions during the cold start process of gasoline
engines, a hydrocarbon catcher coated with ZSM-5 zeolite was manufactured. The post …

We have developed chemical trapping techniques as a novel tool to assess the nature of
unstable reaction intermediates in the standard SCR reaction at low temperatures (120 …
