Transition metal-containing zeolites have received considerable attention, owing to their application in the selective catalytic reduction of NOx. To understand their chemistry, both structural and mechanistic aspects at the atomic level are needed.
This review provides a panoramic view of emission control technologies and key aftertreatment catalysts for vehicles using fossil fuels and carbon-neutral fuels.
In the context of global warming, the emission of the greenhouse gas nitrous oxide (N2O) is an important factor limiting the application of ammonia fuels in marine and offshore power.
This review presents the important progress of Cu-based catalysts for the NH3-SCR reaction. Special attention is given to elucidating the design of high-performance catalysts, as well as anti-inactivation measures in industrial applications.
A volcano-type diagram that identifies the product distribution rule and the optimal activity region for NH3-SCR on rutile-type metal oxides was constructed, which reveals the bifunctional catalysis constraint between metal and lattice oxygen sites.
