Cobalt Phthalocyanine Supported on Mesoporous CeO2 as an Active Molecular Catalyst for CO Oxidation

Yibo Song et al.

Summary: This study immobilized cobalt phthalocyanine (CoPc) molecules on a Ce-based metal-organic framework (Ce-BTC) and converted it to mesoporous CeO2, achieving molecular-level dispersion of CoPc on the surface of CeO2. The resulting CoPc/CeO2 catalysts showed good CO oxidation performance. The mixing manner of Ce-BTC and CoPc significantly affected the physicochemical properties and catalytic performance, indicating the promising potential of Ce-BTC-mediated CoPc loading strategy for heterogenization of catalytic biomolecules.

Identification of Highly Selective Surface Pathways for Methane Dry Reforming Using Mechanochemical Synthesis of Pd-CeO2

Juan D. Jimenez et al.

Summary: The study explored the mechanism of the methane dry reforming reaction using Pd/CeO2 catalysts prepared via mechanochemical synthesis. The results showed that the PdAcCeO2M catalysts had unique Pd-Ce interfaces, leading to enhanced reactivity and a distinct reaction mechanism compared to traditionally synthesized Pd/CeO2 catalysts. The presence of a carbon-modified Pd-0 and Ce-4+/(3+) surface arrangement in PdAcCeO2M was found to activate and sustain distinct Pd-CO intermediate species and strong Pd-CeO2 interactions during the reaction.

Photocatalytic Synthesis of Urea (CO2/N2/H2O) on Coal-Based Carbon Nanotubes with the Fe-Core-Supported Ti3+-TiO2 Composite Catalyst

Halidan Maimaiti et al.

Summary: In this study, Fe-core carbon nanotubes (Fe-CNTs) were prepared using raw coal as a carbon source, and Ti3+ doped TiO2 (Ti3+-TiO2) was loaded onto Fe-CNTs to form Ti3+-TiO2/Fe-CNTs. The photocatalytic co-reduction of N-2/CO2 in H2O was performed, with results showing that the performance was related to the arrangement of Ti3+ sites and oxygen vacancies on the Ti3+-TiO2 surface. The composite catalyst showed significantly increased CO(NH2)2 yield compared to single Ti3+-TiO2, indicating the beneficial role of Fe-CNT support in the photocatalysis.

Yuhan Zhou et al.

Summary: NH3 treatment significantly improves the De-NO efficiency of CeO2 nanorods catalyst, especially in the temperature range of 160-410 degrees C. NH3 treatment promotes the production of Ce3+ on the surface of CeO2 catalyst, leading to more oxygen vacancies and enhanced SCR reaction. Additionally, NH3 treatment disrupts the crystallinity of CeO2 catalyst, enhances its reducibility, and increases the content of active functional groups on the surface.
