V-based NO x abatement systems are limited in operating at low-temperatures due to the formation of ammonium bisulfate that blocks active sites of catalysts. Here, the authors report that physically mixed zeolites trap ammonium bisulfate in their mic

Formic acid is a promising hydrogen source and liquid organic hydrogen carrier because of its high hydrogen density. To produce hydrogen from formic acid, catalytic dehydrogenation of formic acid over Pd-based catalysts has been investigated. Here, a

Selective catalytic reduction of NOx with NH3 (NH3-SCR) in Cu-SSZ-13 has been proposed to have a unique homogeneous-like mechanism governed by the spatial proximity of mobile Cu ions. Among factors that determine the proximity, the effect of ion dens

Cu-SSZ-13 has been successfully commercialized as a NOx removal catalyst for selective catalytic reduction with NH3 (NH3-SCR) in after-treatment systems. However, as global regulations on NOx emissions are becoming more stringent, the development of

The involvement of Lewis and Bronsted acid sites on V2O5/TiO2 catalyst in the selective catalytic reduction of NO with NH3 (NH3-SCR) is under debate. Here, a Li doping strategy is applied to selectively block Bronsted sites, which aims to prepare mod
