Internal combustion engines operating under lean-burn conditions exhibit high fuel efficiency. Removal of harmful NOx gases from the exhaust in the presence of excess oxygen, however, presents a great challenge to the catalysis community. Traditional three-way catalysts are ineffective under these conditions. Therefore, new approaches toward NOx reduction have been sought in the last decade. Urea selective catalytic reduction (SCR), plasma assisted NOx reduction, and NOx storage/reduction (NSR) are three promising technologies for diesel emission control.
