Mechanisms of soot-aggregate restructuring and compaction

Joel C. Corbin et al.

Summary: This study combines theory and experiments to explain conflicting viewpoints on the compaction of soot aggregates. The study finds that internal mixing of soot particles with liquid coatings through condensation typically leads to compaction, while internal mixing through coagulation or the formation of solid or highly viscous coatings may avoid compaction.

Revealing active edge sites induced by oriented lattice bending of Co-CeO2 nanosheets for boosting auto-exhaust soot oxidation

Yuanfeng Li et al.

Summary: In this study, a series of Co-x-CeO2 nanosheet catalysts were synthesized through a one-step hydrothermal method. The CeO2 microsphere with crossed nanosheets enhances the contact efficiency between soot and catalyst, and the substitution of Co ions for cerium sites in CeO2 leads to the oriented bending of Co-CeO2 nanosheets, thereby improving the adsorption/activation properties of NO and O-2. The Co-2-CeO2 catalyst exhibits the highest tolerance to H2O (T-50 = 334 ℃, TOF = 1.32 h(-1)) and excellent stability during soot oxidation in the presence of H2O. The proposed mechanism, supported by characterizations and DFT calculations, suggests that the active edge sites on the Co-CeO2 nanosheets can activate surface oxygen and gaseous O-2, and the active oxygen species can promote the oxidation of NO to NO2, which is a crucial step in the NOx-assisted catalytic mechanism for soot oxidation. This research provides a promising approach for the rational design of high-performance non-noble metal catalysts for practical applications.

Insight into the better performance of Co than Pt on Ce-Sn catalyst for soot oxidation

Meng Wang et al.

Summary: In this study, a 3 %Co/Ce-Sn catalyst displayed higher efficiency in soot oxidation compared to a 1 %Pt/CeSn catalyst. The 3 %Co/Ce-Sn catalyst also exhibited strong resistance to H2O and SO2 poisoning. The introduction of Co induced more oxygen defects, enabling the activation of chemisorbed oxygen and the production of active oxygen species. Furthermore, it was discovered that the oxidation process of NO to NO2 was governed by active oxygen species, which facilitated soot oxidation through a NO2-assisted mechanism. These findings provide valuable insights for the design of cost-effective and high-performance catalysts for soot oxidation, with the 3 %Co/Ce-Sn catalyst being a promising candidate for controlling soot in diesel vehicles.

Soot oxidation over V/ZSM-5 catalysts in a dielectric barrier discharge (DBD) reactor: Performance enhancement by transition metal (Mn, Co and Fe) doping

Jianbin Luo et al.

Summary: The oxidation of soot particles over M-V/ZSM-5 catalysts (M=Mn, Co and Fe) was investigated in a cylindrical DBD plasma reactor. Soot particles were completely eliminated after 60 minutes of reaction in the plasma reactor. Mn-V/ZSM-5 catalyst exhibited higher catalytic activity towards soot particles compared to the Co-V/ZSM-5, Fe-V/ZSM-5, and VOx/ZSM-5 catalysts in the plasma reactor. However, the CO2 selectivity showed an opposite trend to the soot oxidation rate.

Summary: Here, Ru nanoparticles (NPs) were decorated on the S-1 surface using the GBMR method, leading to the formation of an interfacial structure that enhances adsorption/activation properties and catalytic activity. The Ru/S-1 catalyst showed excellent catalytic performance for soot oxidation, with high CO2 selectivity and no obvious deactivation after cycling five times. The interfacial effect between Ru NPs and S-1 played a crucial role in the conversion of NO to NO2 during soot oxidation.

Analyzing the role of copper in the soot oxidation performance of BaMnO3-perovskite-based catalyst obtained by modified sol-gel synthesis br

Veronica Torregrosa-Rivero et al.

Summary: Carbon black can reduce the calcination temperature, but hinder the formation of BaMnO3 polytype. Mixed oxides synthesized at low calcination temperatures have smaller particle size, slightly higher BET surface areas, and smaller macropores. The distribution of copper in the catalysts depends on the calcination temperature, and higher temperature promotes copper insertion into the perovskite structure. BMC3-C600 shows the best performance with high surface copper and oxygen vacancies.
