Removal of NOx emissions from the exhaust of lean-burn vehicles during cold-start conditions has gained immense importance due to the imposition of stringent emission norms from time to time. The commercial deNOx technologies (SCR/LNT) are not efficient enough to curb NOx emissions at low temperatures. Thus, Prateek’s research focused on the development of catalytic materials that can adsorb NOx at low temperatures and reduce the incoming NOx at intermediate and high temperatures. Apart from the development of catalytic materials, Prateek’s research interests include the design of reactor-based studies for the determination of mechanistic aspects involved in the NOx reduction process. Besides, he has also worked on the effect of different reductants/operating conditions on the performance of developed catalytic materials.
