Alkali-Resistant NOx Reduction over SCR Catalysts via Boosting NH3 Adsorption Rates by In Situ Constructing the Sacrificed Sites

Currently, improving the alkali resistance of vanadium-based catalysts still remains as an intractable issue for the selective catalytic reduction of NOx with NH3 (NH3–SCR). It is generally believed that the decrease in adsorbed NHx species deriving from the declined acidic sites is the chief culpri...
