A PGM-free NO x adsorber + selective catalytic reduction catalyst system (AdSCR) for trapping and reducing NO x in lean exhaust streams at low temperature

Low-temperature operation of urea/NH 3 -SCR converters, required by recent emission regulations, is challenging due to technological limits related to poor catalytic activity, difficult urea decomposition and undesired ammonium nitrate formation. Herein, we present a novel concept of a catalytic dev...
