Batch Adsorption of Acid Red 37 (AR37) and Basic Orange 2 (BO2) on amino ethyl-functionalized SBA-15 have been studied. SBA-15 was synthesized and functionalized according to the procedure in the literature. Amino ethyl-functionalized SBA-15 showed the BET surface area 520 m2/g and pore diameter 7.02 nm, based on adsorption-desorption of N2. SEM image shows lengthy fib...

A magnetic nanoparticle conjugated mesoporous nanocatalyst (Fe(3)O(4)@mesoporous SBA-15) with a high surface area has been synthesized by chemical conjugation of magnetite (Fe(3)O(4)) nanoparticles with functionalized mesoporous SBA-15. Functionalized mesoporous SBA-15 containing surface carboxyl and amino groups was synthesized via the thiol-ene click reaction of cysteine hydrochloride and vin...

Magnolol (MG) is a small-molecule neolignan polyphenolic compound isolated from the genus Magnolia. The anti-inflammatory, anti-oxidative, anti-diabetic, anti-tumorgenic, anti-neurodegenerative, anti-depressant and anti-microbial properties of MG are well documented in recent literature. These fascinating multiple biological activities of MG encourage research about the development of new deliv...

Special preparation of Santa Barbara Amorphous (SBA)-15, mesoporous silica with highly hexagonal ordered, these materials have been carried out for creating adsorbents exhibiting an enhanced and partially selective adsorption toward CO₂. This creation starts from an adequate conditioning of the silica surface, via a thermo-alkaline treatment to increase the population of silanol species on it. ...

Mesoporous silica, SBA-15 was successfully functionalized with quinoline moiety, and was applied as a matrix in the MALDI-TOF-MS analysis of small molecules. The modified SBA-15 material [SBA-15-8-(3-(triethoxysilyl)propoxy) quinoline, SBA-15-8QSi] was obtained by using calcined SBA-15 and 8-hydroxy quinoline. The structure of the functionalized mesoporous material was systemically characterize...

Amino-functionalized SBA-15 mesoporous silica was prepared, characterized, and used as an adsorbent for heavy metal ions. The organic–inorganic hybrid material was obtained by a grafting procedure using SBA-15 silica with 3-aminopropyl-triethoxysilane and bis(2,4,4-trimethylpentyl) phosphinic acid (Cyanex 272), respectively. The structure and physicochemical properties of the materials were cha...

Carbon dioxide (CO2) adsorption on unfunctionalized and amino-functionalized SBA-3 materials are investigated and compared in this study. The synthesized materials are characterized by various techniques such as X-ray diffraction (XRD), Brunauer-Emmet-Teller (BET) method, Fourier transform infrared (FT-IR) and Scanning electron microscopy (SEM).The isotherms of these materials have been measure...

Mesoporous silica SBA-15 was synthesized using P123 as surfactant and functionalized with (3-chloropropyl) triethoxysilane. For the first time, the composite of THPP-SBA-15 was prepared using incorporation of tetrakis(4-hydroxyphenyl)porphyrin in functionalized SBA-15. The materials were characterized by BET, SEM, XRD, FT-IR, DRS, and UV–Vis spectroscopy techniques. The synthesized composite wa...

In the present work, results of γ-irradiation on normal and functionalized SBA-15 by aurintricarboxylic acid have been reported. Characterization of normal and functionalized SBA-15 particles before and after γ-irradiation was carried out using Fourier-transform infrared technique. Aurintricarboxylic acid ligand connected to SBA-15 was also analyzed using UV/Vis spectrophotometer. The modified ...

A recoverable Rh/N-SBA-15 heterogeneous catalyst for asymmetric hydroformylation of styrene was prepared by post grafting method. XRD, TG, 29 Si MAS NMR and ICP characterization, revealed that the introduction amino silane RhCl 3 had no adverse influence on ordered mesoporous structure support. The proved to be highly efficacious stable styrene. experimental results demonstrated improved loadin...
