Core-shell catalysts with CoMoS phase embedded in clay nanotubes for dibenzothiophene hydrodesulfurization

Al. A. Pimerzin et al.

Summary: A nanoarchitectural strategy for designing highly active catalysts using CoMoS encased in 50-nm diameter aluminosilicate tubes as a natural support has been proposed. This encapsulation approach protects the active metal sulfides from aggregation, coking, and leaching. Experimental results indicate that the selective loading of molybdenum oxide inside the nanotubes using Mo-heteropolyacid anionic precursor complex leads to the formation of CoMoS particulate core inside the aluminosilicate shell, resulting in a mechanically strong mesoporous catalyst efficient for the hydro treatment of diesel petroleum fraction to clean fuels.

Jing Hong et al.

Summary: The hierarchical dots-core-shell structure Ag@HNT@PZE, combining the catalytic degradation of toxic gases by Ag and enhanced dispersion and flame retardant efficiency by PZE, effectively reduced the flammability and smoke toxicity of EP nanocomposites. The composite exhibited improved fire safety properties with higher LOI, UL-94 grade, and char yield, along with a significant decrease in pHRR and increased graphitized char layer formation. The use of Ag nanoparticles within HNT for catalyzing gas conversion and PZE coating for enhancing flame retardant properties provides a potential solution for developing efficient flame retardants for nanocomposites.

Molybdenum Dioxide Nanoparticles Anchored on Nitrogen-Doped Carbon Nanotubes as Oxidative Desulfurization Catalysts: Role of Electron Transfer in Activity and Reusability

Juncong Zou et al.

Summary: The electron transfer between metal-oxides and supports greatly impacts the performance of catalysts in oxidative desulfurization (ODS), with molybdenum dioxide with oxygen vacancies (V-O-MoO2) catalysts anchored on electron-rich nitrogen-doped carbon nanotubes (NC) showing excellent ODS activity and reusability. By promoting dispersion of V-O-MoO2 and reducing the bond energy of the Mo-O bond, the strong electron-donating effect of NC on V-O-MoO2 enhances exposure of active sites and enriches oxygen vacancies, leading to effective desulfurization.
