“…[50] The results indicated a remarkable reduction in regeneration temperature by 112 °C when using CeO 2 nanofibers coating on a non-catalytic DPF. Gautham et al [51] synthesized CeO 2 nanofibers via a hydrothermal synthesis method and coated them on FeCrAl alloy using a dip coating approach. The soot oxidation capacity of the catalyst was tested in a diesel engine's DPF.…”

Environmental issues exert a significant influence on the human life. Soot particles have attracted attention as a major source of pollution. Significant progress has been made in the research of efficient soot combustion catalysts. The distinctive bonding properties on the 4f orbitals of rare earth elements exhibit excellent catalytic performance for soot combustion. This comprehensive review explores recent advancements in the design of catalysts based on rare earth oxides, with a specific focus on various catalytic materials (La‐based, Ce‐based, Pr‐based and other rare earth elements), synthesis methods, catalyst morphology, catalytic performance and the intricate mechanisms governing their performance in catalytic soot combustion. The activity and selectivity of different rare earth catalysts in various reaction atmospheres are also summarized in the article. Finally, the challenges associated with rare earth oxide‐based catalysts and their potential for future development in the soot combustion are highlighted. This review establishes a fundamental basis for the further design of catalytic materials that exhibit enhanced efficiency and stability.

“…Ceria nanorods were fabricated via a conventional hydrothermal method. 28,29 Ce(NO 3 ) 3 $6H 2 O (1.3 g) and NaOH (7.35 g) were dissolved in deionized water to form homogeneous solutions. The Ce(NO 3 ) 3 $6H 2 O solution was rst poured into a PTFE lining, and then, the NaOH solution poured into the same PTFE lining.…”

A Negative Effect of Niobium‐Doped Ceria on Soot Oxidation Activity^‡

Niobium-doped ceria catalysts were synthesized to study soot oxidation activity. X-Ray diffraction (XRD) and Raman analysis of the samples revealed the presence of a fluorite structure of CeO 2 for all the doped samples. The T 50 temperature of the pure CeO 2 sample was more significant than that of bare soot. The high catalytic activity of the CeO 2 catalyst can be attributed to the low crystallite size, high facet ratio, and the large Brunauer-Emmett-Teller (BET) surface area as compared to Nb-doped samples. The activation energy calculated by both Ozawa and KAS methods were found to be low for CeO 2 when compared to Nb-doped samples. CeO 2 resulted in better soot oxidation activity with low activation energy.
