Preparation and thermal properties of mesoporous silica/phenolic resin nanocomposites via in situ polymerization [PDF]

open access: yeseXPRESS Polymer Letters, 2012
In order to enhance the adhesion between inorganic particles and polymer matrix, in this paper, the mesoporous silica SBA-15 material was synthesized by the sol-gel method. The surface of SBA-15 was modified using γ-glycidyloxypropyltrimethoxysilane

Effects of Pore Size and Crosslinking Methods on the Immobilization of Myoglobin in SBA-15

open access: yesFrontiers in Bioengineering and Biotechnology, 2022
A series of stable mesoporous silica sieves (SBA-15) with different pore sizes (9.8, 7.2, and 5.5 nm) were synthesized using a hydrothermal method. The resulting mesoporous material was then utilized for protein immobilization using myoglobin (Mb) as the

Influence of Adding Molybdenum on Structure and Performance of FexOy/SBA‐15 Catalysts in Selective Oxidation of Propene [PDF]

open access: yes, 2019
Mixed iron and molybdenum oxide catalysts supported on nanostructured silica, SBA‐15, were synthesized with various Mo/Fe atomic ratios ranging from 0.07/1.0 to 0.57/1.0. Structural characterization of as‐prepared MoxOy_FexOy/SBA‐15 samples was performed

Influence of calcination conditions on structural and solid‐state kinetic properties of iron oxidic species supported on SBA‐15 [PDF]

open access: yes, 2019
Iron oxidic species supported on silica SBA-15 were synthesized with various iron loadings using two different FeIII precursors. The effect of varying powder layer thickness during calcination on structural and solid-state kinetic properties of FexOy/SBA-

Catalytic combustion of benzene on Co/CeO2/SBA-15 and Co/SBA-15 catalysts [PDF]

open access: yesCatalysis Communications, 2008
Catalytic oxidation of benzene was investigated on Co/CeO2/SBA-15 and Co/SBA-15 catalysts. These catalysts were characterized by X-ray diffraction, N2 sorption and temperature programmed reduction (TPR) methods. The results show that Co3O4 are not well dispersed on CeO2/SBA-15.

Ordered mesoporous silica materials for protein adsorption [PDF]

open access: yes, 2007
Lysozyme and BSA were used, as model proteins of considerably different dimensions, in order to evaluate the influence of the distinct pore structural characteristics of three types of ordered mesoporous silica materials (MCF, SBA-15 and MCM-41) on ...

Selective Hydrogenation of the Carbonyls in Furfural and 5-Hydroxymethylfurfural Catalyzed by PtNi Alloy Supported on SBA-15 in Aqueous Solution Under Mild Conditions

open access: yesFrontiers in Chemistry, 2021
Valuable furfuryl alcohol (FFA) and 2,5-dihydroxymethylfuran (DHMF) could be produced by selective hydrogenation of biomass-derived furfural (FF) and 5-hydroxymethylfurfural (HMF) with high atom economy. In this study, SBA-15 (a kind of mesoporous silica

Microwave-assisted embedding of bis-vanillin and bis-eugenol into SBA-15: Synthesis of chemosensors precursors for the detection of metal cations [PDF]

open access: yes, 2017
In this work we evaluate the necessary experimental conditions to carry out the embedding of bis-vanillin and bis-eugenol, two potential precursors of chemosensors, in the porous structure of the mesoporous silica SBA-15 through a microwave assisted ...
