Abstract
A novel NO x -storage-reduction process is proposed in an electric field which works even in lean-burn conditions (8% O 2 ) at 423 K. 3 wt% Pt–16 wt% BaO/CeO 2 catalyst shows markedly higher NO x conversion to N 2 (13.1% vs . 2.9% without an electric field) even in lean-burn conditions with 8% O 2 .
