A protonated polyaniline-functionalized SBA-15 mesoporous silica nanomaterial (H(+)-PANI/SBA-15) with high surface area and ideal surface properties for the adsorption of anionic dyes is synthesized. Compared with the conventional emeraldine salt of polyaniline (H(+)-PANI), H(+)-PANI/SBA-15 has a significantly higher adsorption capacity for the anionic dye Orange G and is a more effective sorbe...

Soybean agglutinin (SBA) is a non-fiber carbohydrate-related protein and the main anti-nutritional factor that exists in soybean or soybean products. SBA possesses a specific binding affinity for N-glyphthalide-d-galactosamine or galactose and has a covalently linked oligosaccharide chain. SBA mediates negative effects on animal intestinal health by influencing the intestinal structure, barrier...

We formally deene the set-based abstraction of any language whose operational semantics can be deened by environment evaluation. The Aiken-Wimmers soft type system precisely corresponds to this set-based abstraction under their operational semantics. The Heintze set-based analysis is precisely this set-based abstraction under a diierent operational semantics. In general, set-based abstraction d...

The adsorption and activation of both CO2 methanol are mainly affected by the distance Lewis acid site, Zr4+, base, Zr4+/O2−, Zr-based catalysts. In this paper, Zr-incorporated SBA-15 (Zr-SBA-15) Zr-grafted (Zr/SBA-15) catalysts were prepared with different Zr environments, analyzed N2 adsorption–desorption isotherms, X-ray diffraction, UV-vis spectra, XPS. It was proposed that Zr-SBA-15 cataly...

Tuning the morphological and acidic properties of mesoporous molecular sieve materials is highly valuable for catalyst design towards reactions involving large molecules. In this work, a series Ga-containing SBA-15 ordered (OMMs) were synthesized following acid-free strategy. Ga-SBA-15 exhibits an acid amount 0.48 mmol/g, comparable to Al-SBA-15 (0.45 mmol/g). addition, it found that straight s...

A series of vanadia catalysts supported on SBA-15 (V/SBA) with a vanadia (V) content ranging from 1% to 11% were prepared by an incipient wetness method. Their catalytic behavior in the dehydrogenation of isobutane to isobutene with CO2 was examined. The catalysts were characterized by N2 adsorption, X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman spectroscopy, and temperatur...

INTRODUCTION Confinement of biomolecules in structured nanoporous materials offers several desirable features ranging from chemical and thermal stability, to resistance to degradation from the external environment. A new generation of mesoporous materials presents exciting new possibilities for the formulation and controlled release of biological agents. Such materials address niche application...

We report the preparation of highly ordered mesoporous Fe-Al-SBA-15 with isolated extraframework Fe species under acidic conditions. The materials were characterized by means of UV resonance Raman spectroscopy, in conjunction with BET, XRD, TEM, UV-vis, H2-TPR, FT-IR, and 27Al MAS NMR spectroscopy. The addition of both Fe and Al to the synthesis gel of SBA-15 results in the formation of isolate...

Vanadium oxide grafted on mesoporous silica SBA-15 has been synthesized using a controlled grafting process. Its structure has been thoroughly investigated using different characterization techniques, including N2-physisorption, X-ray diffraction, transmission electron microscopy (TEM), Raman spectroscopy, H2 temperature-programmed reduction, X-ray absorption near-edge structure (XANES), and ex...

Luminescence functionalization of the ordered mesoporous SBA-15 silica is realized by depositing a CeF3: Eu3+ phosphor layer on its surface (denoted as CeF3: Eu3+/SBA-15/IS, CeF3: Eu3+/SBA-15/SI and CeF3: Eu3+/SBA-15/SS) using three different methods, which are reaction in situ (I-S), solution impregnation (S-I) and solid phase grinding synthesis (S-S), respectively. The structure, morphology, ...
