    Amine-Functionalized Ordered Mesoporous Silica

    The synthesis, characterization, and catalytic behavior of several amine-functionalized ordered mesoporous silica (OMS) materials are reported. All samples show catalytic activity for the conversion of glyceryl tributyrate with methanol to methyl esters in high yield (>60%). The reactivity of the amines approximately correlates with the pK values of the free amines. The effect of the amine

    Amine‐functionalized ordered mesoporous silicas as model

    Uptake of dilute aqueous acetic acid was compared using primary, secondary, tertiary amines, and quaternary ammonium grafted ordered mesoporous silica. Primary amine and quaternary ammonium grafted samples showed the highest uptake, 0.21 mmol acetic acid/g SBA‐15, with secondary and tertiary amines showing nominally lower, 0.18 mmol/g, at 0.5

    Amine‐functionalized mesoporous silica: A material capable

    The surface of ordered mesoporous (MCM‐48) silica has been subjected to covalent grafting with silane molecules containing one to three amino groups. The dielectric properties of the materials were studied in detail, and the functionalized materials were used for CO 2 adsorption at room temperature, followed by regeneration under either

    One-step synthesis of amine-functionalized hollow mesoporous

    In this study, amine-functionalized hollow mesoporous silica nanoparticles with an average diameter of ~100 nm and shell thickness of ~20 nm were prepared by an one-step process. This new nanoparticulate system exhibited excellent killing efficiency against mycobacterial (M. smegmatis strain mc 2 651) and cancer cells (A549).

    Direct synthesis of highly ordered amine-functionalized

    Highly ordered amine-functionalized mesoporous ethane-silicas have been synthesized with P123 as the template under acidic conditions via a simple direct co-condensation method. Addition of inorganic salt KCl during the synthesis can reduce the interference effect of the amine moiety on the co-assembly process and hence increase the structural

    Insights into the CO2 capture over amine-functionalized

    Ordered mesoporous silicas were synthesized via cooperative self-assembly with Pluronic P123 (EO 20 PO 70 EO 20, Sigma-Aldrich) or BrijC10 (C 16 H 33 (OCH 2 CH 2) 10 OH, Sigma-Aldrich) as pore structure-directing templates and Na 2 SiO 3 (8.6 wt.% SiO 2) from RHA as a silica source .

    Amine-Functionalized Mesoporous Silica @ Reduced Graphene

    Amine-functionalized mesoporous silica @ reduced graphene (denoted as mSiO2@rGO-NH2) sandwichlike structure materials are synthesized via an oil–water stratification method and the self-assembled monolayers on mesoporous support (SAMMS) technique. The resulting mSiO2@rGO-NH2 materials exhibit excellent performance for physical and chemical synergetic adsorption of CO2 gas. Among them, with
