Formation mechanism of SBA-16 spheres and control of their dimensions

Microporous and Mesoporous Materials, 2006
Abstract Using a quaternary mixture of surfactant F127, demineralized water, HCl and butanol, it is possible to form different sized spheres of SBA-16 only by controlling the amount of siliceous precursor (TEOS) used during the synthesis. These spheres are well ordered and show very high porosity.

Tetraethylenepentamine impregnated composite material ZSM-5/SBA-16 for CO2 adsorption

Journal of Materials Research, 2022
A stable and effective amine-modified adsorbent for CO2 capture was prepared with the impregnation method using the ZSM-5/SBA-16 (ZS) as support and the tetraethylenepentamine (TEPA) as modifier. The CO2 adsorption performance was investigated by thermal

Catalytic partial oxidation of methanol over Au–Pd bimetallic catalysts: a comparative study of SBA-16, SBA-16-CeO2, and CeO2 as supports

Transition Metal Chemistry, 2011
Au–Pd catalysts supported on SBA-16, SBA-16-CeO2, and CeO2 had been studied for partial oxidation of methanol to produce H2. The physicochemical characteristics of the catalysts prepared by deposition–precipitation using urea hydrolysis were examined by inductively coupled plasma atomic emission spectroscopy (ICP-AES), Brunauer-Emmett-Teller (BET), X ...

Quantitative analysis of defects and domain boundaries in mesoporous SBA-16 films

Micron, 2007
Some quantitative structural analyses on defects and domain boundaries observed in SBA-16 films were performed using the lattice concept and geometric phase method. These analyses show that there exist low angle, high angle and translational anti-phase domain boundaries in SBA-16 films.

Highly CO2 selective mixed matrix membranes of polysulfone based on hetaryl modified SBA-16 particles

, 2021
Mixed matrix membranes were prepared by incorporating pyrazole functionalized SBA-16 type mesoporous silica as filler in polysulfone (PSf) matrix. The structure, morphology, and porosity of functionalized filler were confirmed by Fourier transform ...

Liquid adsorption of n-octane/octanol/ethanol on SBA-16 silica

Journal of Colloid and Interface Science, 2007
SBA-16 silica samples with cubic Im3 m symmetry were synthesized according to methods reported in literature and characterized by nitrogen adsorption and X-ray diffraction. The adsorption behavior of the n-octane(1)/octanol(2), n-octane(1)/ethanol(3), and octanol(2)/ethanol(3) binary liquid mixtures on SBA-16 was studied over the whole concentration ...

In vitro study of aripiprazole loading and releasing efficiency of SBA-16

Journal of Porous Materials, 2020
Mesoporous silica (SBA-16) was synthesized by the hydrothermal synthesis route. The structural properties of the synthesized SBA-16 were found out by a small-angle X-ray diffraction technique. Morphological characterization was characterized by scanning electron microscope (SEM) and high-resolution transmission electron microscope (HRTEM).

Nickel-based nanocrystals dispersed on SBA-16 gels: Synthesis and structural characterization [PDF]

Journal of Non-Crystalline Solids, 2014
Porous monoliths of nanocomposites containing Ni (5 wt.%) and FeNi (5 wt.%) nanoparticles dispersed on an SBA-16 type matrix were prepared following a templated-gelation method based on the sol–gel process. The nanocomposites were characterized by energy dispersive X-ray spectroscopy, N2 physisorption at 77 K, X-ray diffraction and transmission and ...
