Decatungstate W(10)O(32)(4-) heterogenized on a novel hydrophobically-organomodified SBA-15 was proven an efficient, green and reusable catalyst for photooxygenation by oxygen of a range of aryl alkanes to the corresponding ketones under mild conditions.

This work presents two easy ways for preparing nanostructured mesoporous composites by interconnecting and combining SBA-15 with mixed oxides derived from a calcined Mg-Al hydrotalcite. Two different Mg-Al hydrotalcite addition procedures were implemented, either after or during the SBA-15 synthesis (in situ method). The first procedure, i.e., the post-synthesis method, produces a composite mat...

SBA-15 is an interesting mesoporous silica material having highly ordered nanopores and a large surface area, which is widely employed as catalyst supports, absorbents, drug delivery materials, etc. Since it has a lack of functionality, heteroatoms and organic functional groups have been incorporated by direct or post-synthesis methods in order to modify their functionality. The aim of this art...

Tungsten oxide nanoclusters supported highly ordered mesoporous SBA-15 material has been successfully synthesized in a single step using a non-ionic surfactant as a template and used for the selective oxidation of sulfur compounds, giving excellent yields at room temperature with exceptional catalyst recyclability.

In the present work, mesoporous SBA-15 and SBA-16 were synthesised using classical methods, and their physicochemical properties were investigated by X-ray diffraction (XRD), FTIR, TEM and N2 adsorption-desorption. Rhodium (Rh, 1 wt %) was loaded on the mesoporous SBA-15 and SBA-16 by an impregnation method. The Rh surface coverage, dispersion and crystallite size were determined by room temper...

In the context of removal biochemical oxygen demand (BOD5) from food and beverages production wastewaters, this paper reports capabilities SBA-15 modified with (3-aminopropyl)-triethoxysilane (S-APTES) N-[3-(trimethoxysilyl)propyl]aniline (S-Aniline) in glucose, fructose sucrose at very high concentrations (350,000 mg/L for 350,000 170,000 sucrose), i.e. sugars most widely used as sweeteners be...
