“…It bears merely weak hydrogen bonding Si–OH sites and therefore at most only slightly acidic 47 , 48 . Its acidity could be improved, however, by substituting the Si atoms on its surface with Al 49 , B 50 , and Zn 51 , and or by functionalizing the MCM-41 surface with an alkyl sulfonic acid anchoring group 52 , 53 , succinamic acid 54 , or –SO 3 H 55 – 57 . Due to a large number of silanol groups, anchoring of inorganic –SO 3 H to the MCM-41 surface is very practical 58 .…”

A library of new spiro[diindeno[1,2-b:2′,1′-e]pyridine-11,3′-indoline]-2′,10,12-trione derivatives has been prepared in an efficient, one-pot pseudo four-component method mediated by a reusable heterogeneous nano-ordered mesoporous SO3H functionalized-silica (MCM-41-SO3H) catalyst. Excellent yields, short reaction times, as well as convenient non-chromatographic purification of the products and environmental benefits such as green and metal-free conditions constitute the main advantages of the developed synthetic methodology. The obtained fused indole-indenone dyes would be of interest to pharmaceutical and medicinal chemistry. Furthermore, due to their sensitivity to pH changes, they could be used as novel pH indicators.

“…The peaks at 450 cm –1 and 1074 cm –1 in the spectrum of MCM‐41 are due to the symmetric stretching vibration of the Si–O–Si bond, which are the feature peaks of MCM‐41 . For NaHSO 4 , the bands at 1220 cm –1 and 589 cm –1 are attributed to the symmetric stretching vibration of O–SO 2 –O . Moreover, the peaks at 2854 cm –1 and 2926 cm –1 in the spectrum of DTEOS/MCM‐41 are assigned to the symmetric stretching vibration and asymmetric stretching vibration of the –CH 2 – bond, respectively .…”

n-Dodecyltriethoxysilane (DTEOS) modified NaHSO 4 / MCM-41 catalysts (silanized catalysts) were synthesized by different impregnation sequences and evaluated in the liquid-phase dehydration of castor oil. The samples were evaluated by X-ray diffraction, nitrogen adsorption-desorption, SEM, TEM, FT-IR spectroscopy, XPS, 29 Si MAS NMR spectroscopy, contact angle measurements, NH 3 -TPD, and pyridine-FT-IR spectroscopy. The analyses demonstrated that silanization enhanced the hydrophobicity of the catalysts, and the impregna-* Prof. Dr. J.-F. Ding E-Mail : ycitjfding@sina.com [a] School of Chemical Engineering

“…However, the wetting process was lower for the solvents with a higher surface energy for water, and this relatively decreased surface adsorption. In other works, ethylene glycol was used as a solvent for chemical grafting of amines which indicated a low amount of aminosilane incorporated onto the INAD [62]. When organic solvents such as cyclohexane and toluene are used as anhydrous products, the evaluation of amine grafting at the INAD surface takes a long time (20 h) for the 3-aminopropyltetraethoxysilane using the reflux method [63].…”

Advances in Amine-Surface Functionalization of Inorganic Adsorbents for Water Treatment and Antimicrobial Activities: A Review

2022

View full text Add to dashboard Cite

In the last decade, adsorption has exhibited promising and effective outcomes as a treatment technique for wastewater contaminated with many types of pollutants such as heavy metals, dyes, pharmaceuticals, and bacteria. To achieve such effectiveness, a number of potential adsorbents have been synthesized and applied for water remediation and antimicrobial activities. Among these inorganic adsorbents (INAD), activated carbon, silica, metal oxide, metal nanoparticles, metal–organic fibers, and graphene oxide have been evaluated. In recent years, significant efforts have been made in the development of highly efficient adsorbent materials for gas and liquid phases. For gas capture and water decontamination, the most popular and known functionalization strategy is the chemical grafting of amine, due to its low cost, ecofriendliness, and effectiveness. In this context, various amines such as 3-aminopropyltriethoxysilane (APTES), diethanolamine (DEA), dendrimer-based polyamidoamine (PAMAM), branched polyethyleneimine (PEI), and others are employed for the surface modification of INADs to constitute a large panel of resource and low-cost materials usable as an alternative to conventional treatments aimed at removing organic and inorganic pollutants and pathogenic bacteria. Amine-grafted INAD has long been considered as a promising approach for the adsorption of both inorganic and organic pollutants. The goal of this review is to provide an overview of surface modifications through amine grafting and their adsorption behavior under diverse conditions. Amine grafting strategies are investigated in terms of the effects of the solvent, temperature, and the concentration precursor. The literature survey presented in this work provides evidence of the significant potential of amine-grafted INAD to remove not only various contaminants separately from polluted water, but also to remove pollutant mixtures and bacteria.
