Modified Sba 15(修改后的 Sba 15)研究综述
Modified Sba 15 修改后的 Sba 15 - CeO2 modified SBA-15 composites have been prepared by adding cerium precursor (Ce(NO3)3·6H2O) directly into the mixture of soft template (P123), silica precursor (TEOS) and urea aqueous solution but without mineral acid. [1] In this work, tris(hydroxymethyl)aminomethane-Zirconium complex supported on modified SBA-15 (SBA-15@n-Pr-THMAM-ZrO) prepared as a novel mesoporous catalyst. [2] The nanoabsorbent was prepared by the Michael addition of amino-modified SBA-15 with methyl acrylate and subsequent amidation with diethylenetriamine (DETA). [3] Thus, in this paper, we attempted to summarize the synthesis procedures, various functionalization processes, and application of metal modified SBA-15 in organic synthesis, fine chemical synthesis, photocatalysis, and decontamination of water. [4] Then, the fluorescent sensor CQDs@Cu-IIP was prepared using a surface imprinting technique with the modified SBA-15 as the substrate, copper ions as a template, tetraethoxysilane as the crosslinker, and 3-aminopropyl-3-ethoxysilane as the functional monomers. [5] Cu+-modified SBA-15 (Cu+/SBA-15, SBA-15 refers well-ordered hexagonal mesoporous silica) was prepared for adsorption of tetracycline (TC) by the pH adjusting reduction method. [6] Silica SBA-15 without removal of template P123 was calcined in an inert atmosphere and the carbon-modified SBA-15 thus obtained was used as the support of Pd catalyst for the hydrogenation of 2-ethylanthraquinone (EAQ). [7] In this paper, water-in-oil (W/O)-type Pickering high-internal phase emulsions (Pickering HIPEs) were stabilized using the modified SBA-15 with appropriate wettability as the stable particle. [8] Preferential and competitive hydrogen bonding-promoted adsorption of urea over hippuric acid in binary mixtures occurred for the APTES-modified SBA-15 adsorbents, as demonstrated using the FTIR spectra of the adsorbents before and after adsorption. [9] The results showed that the aminosilane-modified MCM-41 from slurry and aminosilane-modified SBA-15 from pure silica have the highest adsorption capacities of 1. [10] The lanthanum cations loaded into piperazine-modified SBA-15 was synthesized in three steps, and it was utilized as nanocontainers for inorganic corrosion inhibitor. [11] Functionalized SBA-15 (immobilization of Pd on the modified SBA-15) has been used as an efficient catalyst for the preparation of spiroindolines by multi-component reactions of isatins, cyclic-1,3-diketones, and 6-amino-1,3-dimethyluracil under ultrasonic irradiation in water. [12] A novel Pd (0) nanoparticles anchored over cyano modified SBA-15 was synthesized and characterized with different physicochemical techniques like Transmission Electron Microscopy (TEM), Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive X-ray Spectroscopy (EDX), N2 adsorption-desorption isotherm, X-ray elemental mapping and X-ray Photoelectron Spectroscopy (XPS). [13] In this work we modified SBA-15 adsorbents by functionalization with (3-aminopropyl)-triethoxysilane (SBA-15-APTES) and N-[3-(trimethoxysilyl)propyl]aniline (SBA-15-AN) aiming to use them for the first time in the clean-up step of a QuEChERS (quick, easy, cheap, effective, rugged and safe) extraction of micropollutants from strawberry, a sugar rich fruit. [14] The aim of this study was to analyze the modification of sulindac release profiles in various pH levels with two APTES ((3-aminopropyl)triethoxysilane)-modified SBA-15 (Santa Barbara Amorphous-15) silicas differing in 3-aminopropyl group content. [15] This work presents the synthesis and characterization of hollow silica particles that were fabricated with the asymmetric methyltrimethoxysilane (MTMS) as the only silica precursor, by using a modified SBA-15 synthesis method, for the first time. [16] The glycerol hydrogenolysis reaction proceeds through a dehydration–hydrogenation process, and the enhanced 1,3-PDO selectivity greatly benefited from the synergism between Bronsted acid and Lewis acid sites, which is tightly related with the incorporation of tungsten and aluminum species on the modified SBA-15. [17] BACKGROUND In this study, SBA-15 was functionalized by silane coupling reagents, then lipase from Thermomyces lanuginosus (TLL) was immobilized onto the parent and the organically-modified SBA-15 for diacylglycerols (DAG) production through glycerolysis. [18] Molybdovanadylphosphoric acid (HPMV) was supported on a carbon nitride-modified SBA-15 (CN-SBA-15) molecular sieve to enhance its catalytic performance for oxidation of methacrolein (MAL) to methacrylic acid (MAA). [19] The BFae2 encapsulated in hydrophobic-modified SBA-15 endured up to seven reaction cycles while the BFA activity remained above 60%. [20] P,P-bis (2-oxooxazolidin-3-yl)-N-(3-(triethoxysilyl)propyl)phosphinic amide (APTES-BOP)-modified SBA-15 (SBA-15-BOP) was prepared by a post-synthesis grafting method for the removal of anionic azo dyes from aqueous solutions. [21] In this work, we report a Cu catalyst supported on La-modified SBA-15, where the Cu–LaOx interface is generated through the interaction of highly dispersed Cu nanoparticles with LaOx species bedded into the SBA-15 pore wall. [22] The capacity of 2 mg of modified SBA-15was found to be 123. [23] The functional monomers were anchored to the azide-modified SBA-15 by azide-alkyne Click reaction. [24] Modified SBA-15 catalyst was less stable at the studied conditions. [25] W-SBA-15 were synthesized by immobilizing tungsten species on modified SBA-15 and first used in the aldehydes oxidation reaction. [26] In this work, the potential of the modified SBA-15 surface was examined as a sorbent to load the drug from an aqueous solution; this was done using a post-synthesis function procedure. [27] The synthesized SBA-15 as a support was grafted with various organosilanes in order to acquire the acid-modified SBA-15 (SBA-A), acid- and hydrophobicity-modified SBA-15 (SBA-AC), and base-modified SBA-15 (SBA-N) catalysts. [28] 0 wt% Pd over unmodified SBA-15 (30Pd/SBA-15). [29] The basicity of the modified SBA-15 increased with rising TiN loading. [30] In this work, SBA-15 and carbon modified SBA-15 supported 1wt% Pt catalysts were synthesized and characterized for vapour phase dehydrogenation of decalin. [31] In this work, five different metal-oxide (ZnO, La2O3, CeO2, NiO and MgO) modified SBA-15 (MeO-SBA-15) samples were prepared by a simple one-pot synthesis method and were used in the catalytic cracking of waste cooking oils. [32]将铈前驱体(Ce(NO3)3·6H2O)直接加入软模板(P123)、二氧化硅前驱体(TEOS)和尿素水溶液的混合物中制备CeO2改性SBA-15复合材料，但不添加无机酸。 [1] 在这项工作中，三（羟甲基）氨基甲烷-锆络合物负载在改性 SBA-15 (SBA-15@n-Pr-THMAM-ZrO) 上，制备了一种新型的介孔催化剂。 [2] 纳米吸收剂是通过迈克尔加成氨基改性的 SBA-15 与丙烯酸甲酯并随后与二亚乙基三胺 (DETA) 进行酰胺化来制备的。 [3] 因此，在本文中，我们试图总结金属改性SBA-15的合成过程、各种功能化过程以及在有机合成、精细化工合成、光催化和水净化中的应用。 [4] 然后，以改性SBA-15为基底，铜离子为模板，四乙氧基硅烷为交联剂，3-氨基丙基-3-乙氧基硅烷为功能单体，采用表面印迹技术制备了荧光传感器CQDs@Cu-IIP。 . [5] 通过pH调节还原法制备了Cu+-修饰的SBA-15（Cu+/SBA-15，SBA-15是指有序六方介孔二氧化硅）用于吸附四环素（TC）。 [6] 将不去除模板P123的二氧化硅SBA-15在惰性气氛中煅烧，并将由此获得的碳改性SBA-15用作2-乙基蒽醌（EAQ）氢化的Pd催化剂的载体。 [7] 在本文中，使用具有适当润湿性的改性SBA-15作为稳定颗粒来稳定油包水（W / O）型Pickering高内相乳液（Pickering HIPEs）。 [8] 对于 APTES 改性的 SBA-15 吸附剂，二元混合物中尿素对马尿酸的优先和竞争性氢键吸附促进吸附，如吸附前后吸附剂的 FTIR 光谱所示。 [9] 结果表明，来自浆料的氨基硅烷改性的 MCM-41 和来自纯二氧化硅的氨基硅烷改性的 SBA-15 具有最高的吸附容量，为 1。 [10] 负载于哌嗪修饰的SBA-15中的镧阳离子分三步合成，并将其用作无机缓蚀剂的纳米容器。 [11] 功能化的 SBA-15（将 Pd 固定在改性的 SBA-15 上）已被用作通过靛红、环状 1,3-二酮和 6-氨基-1 的多组分反应制备螺二氢吲哚的有效催化剂，水中超声波照射下的 3-二甲基尿嘧啶。 [12] 合成了一种锚定在氰基改性 SBA-15 上的新型 Pd (0) 纳米颗粒，并采用不同的物理化学技术进行了表征，例如透射电子显微镜 (TEM)、场发射扫描电子显微镜 (FESEM)、能量色散 X 射线光谱 (EDX)、N2吸附-解吸等温线、X 射线元素映射和 X 射线光电子能谱 (XPS)。 [13] 在这项工作中，我们通过使用 (3-氨基丙基)-三乙氧基硅烷 (SBA-15-APTES) 和 N-[3-(三甲氧基甲硅烷基)丙基]苯胺 (SBA-15-AN) 对 SBA-15 吸附剂进行了改性，旨在将它们用于首次在 QuEChERS（快速、简单、便宜、有效、坚固且安全）的净化步骤中从草莓（一种富含糖的水果）中提取微量污染物。 [14] 本研究的目的是分析使用两种 APTES（（3-氨基丙基）三乙氧基硅烷）改性的 SBA-15（Santa Barbara Amorphous-15）二氧化硅（3-氨基丙基含量不同）对不同 pH 水平下舒林酸释放曲线的改性。 [15] nan [16] nan [17] nan [18] nan [19] nan [20] nan [21] nan [22] nan [23] nan [24] nan [25] nan [26] nan [27] nan [28] nan [29] nan [30] nan [31] nan [32]
