A lean NO x trap (LNT) catalyst has been widely used for removing NO x exhaust from lean-burn engines. However, the operation range of LNT has been limited because of the poor activity of LNT catalysts at low temperatures (≤300 °C), especially in

Selective catalytic reduction of NOx by urea (urea/SCR) and Lean NOx Trap (LNT) are two leading technologies for NOx reduction under lean condition. To quickly warm up SCR catalysts, considerable efforts have been made in integrating SCR onto a diese

A series of LTA zeolites with Si/Al = 8.3-∞ and a UFI zeolite with Si/Al = 11 are synthesized using benzylimidazolium-based cations as organic structure-directing agents in fluoride media, if required, together with the tetramethylammonium ion. Two

A combination of the Pt-BaO/CeO2 and Cu/CeO2 (PBC + CC) catalyst offers high NOx storage and reduction (NSR) performance at low temperatures; however, the PBC + CC catalyst is prone to deactivation upon hydrothermal aging. In this study, we used a re
