Mechanism understanding of NOx storage, release and reduction on Pt/Doped ceria catalysts Oisin Hamill (24168759) PUREID: 591271819 NOx storage and reduction NOx abatement automotive emission control lean NOx traps diesel engine ceria RE doped ceria samarium ceira pt-ceria This doctoral thesis addresses the pressing need for advanced emission control technologies in diesel engines to meet stringent governmental regulations targeting harmful pollutants, especially nitrogen oxides (NOx). <br><br>Catalysis, particularly involving ceria doped with rare earth metals, is a promising avenue for enhancing NOx reduction in diesel exhausts. The study explores the substantial impact of rare earth metal doping, specifically utilising samarium (Sm), on the low-temperature NOx storage capabilities of ceria-based catalysts, including platinum* ceria catalysts with varied platinum loadings.<br><br>Through diverse characterisation techniques, the research investigates the complexities between RE metal addition, especially Sm, surface chemistry modifications, and resulting behaviours related to NOx storage and reduction.<br> 2026-10-01T16:38:21Z Text Thesis 10.17034/32639637.v1 https://figshare.com/articles/thesis/Mechanism_understanding_of_NOx_storage_release_and_reduction_on_Pt_Doped_ceria_catalysts/32639637 All Rights Reserved
