Aerobic oxidative desulfurization via magnetic mesoporous silica-supported tungsten oxide catalysts

Synthesis, characterization, and catalytic function of novel highly dispersed tungsten oxide catalysts on mesoporous silica

The physical and chemical properties of tungsten oxide supported on SBA-15 mesoporous silica prepared by a controlled grafting process through atomic layer deposition (ALD) were studied using complementary characterization methods. X-ray diffraction, optical absorption, and transmission electron microscopy showed that tungsten oxide species are highly dispersed on SBA-15 surfaces, even at 30 wt...

Mesoporous silica-supported zirconocene catalysts for highly isotactic polypropylene.

A new bis(indenyl)zirconocene bearing a pendant Si-Cl anchor has been grafted onto MCM-41, SBA-15, MCM-48 and a disordered mesoporous silica for the polymerisation of ethylene and propylene, producing polymers with very high molecular weights, low polydispersities and, in the case of polypropylene, higher levels of isotacticity than obtainable with analogous homogeneous systems.

Nanostructured manganese oxide clusters supported on mesoporous silica as efficient oxygen-evolving catalysts.

Nanostructured Mn oxide clusters supported on mesoporous silica KIT-6 efficiently evolve O(2) in aqueous solution under mild conditions.

Surface Chemistry of Silica-Titania-supported Chromium Oxide Catalysts

The interaction of chromium oxide with different titania-silica supports has been examined. The oxide supports investigated consisted of SiO,, TiO, , physical mixtures of TiO, and SiO,, a surface titania overlayer on SiO, (10% of theoretical monolayer) and a surface silica overlayer on TiO, (80% of theoretical monolayer). The supported chromium oxide catalysts were structurally characterized wi...
