The interfacial mechanism has always been a concern for 3-aminopropyltriethoxysilane (APTES)-grafted palygorskite (PAL). In this research, the of graft modification grafting APTES to surface PAL (100) was studied using density functional theory (DFT) calculation. results illustrated that different states influence inter- and intramolecular interactions between APTES/PAL (100), which are reflect...

Chitosan crosslinked with 3-aminopropyltriethoxysilane was coated on porous poly (L-lactic acid) nanofibrous membrane to remove dyes from wastewater in the present study. The adsorption capacity of composite for removal methylene blue and rhodamine B comprehensively studied. Large framework provided a high surface area effectively immobilize cross-linked chitosan membranes. Batch trials were pe...

The goal of this work is to investigate the effectiveness amorphous SiO2−FexOy loaded by functionalization with Ce(SO4)2, Li2SO4, and 3-aminopropyltriethoxysilane (APTES) for CO2 adsorption. Silica iron-based materials are gaining popularity due their wide range applications, such as catalysis, photocatalysis, imaging, etc.; however, there very few studies regarding adsorption aforementioned ma...

In this study, removal of Acid blue 62 from aqueous solution by mesoporous silicate MCM-41 modified by Aminopropyltriethoxysilane (APTES) composite was studied. Properties of synthesized composite were analyzed and confirmed by SEM, EDX and FTIR. Results show that Langmuir adsorption isotherm has the best compatibility with the results of experiments. Kinetic analysis using pseudo-first-order m...

At present, the widespread use of iron oxide nanoparticles, including for commercial purposes, requires strict preservation their phase composition during application. The choice nanoparticle modifier and modification conditions is decisive due to high sensitivity oxygen in case using real (O2, pH change, etc.). In this work, we studied change magnetite nanoparticles after with 3-aminopropyltri...

A TiO2-coated net with photocatalytic antibacterial properties that purifies water for practical use in developing countries was fabricated. The TiO2 particles were modified a silane coupling agent, aminopropyltriethoxysilane or hexadecyltrimethoxysilane, to improve particle dispersibility. comprises three layers: TiO2-silicone photocatalyst layer, silicone layer protect the substrate from oxid...

The present work focuses on the synthesis of Fe 3 O 4 magnetite core@shell type nanoparticles modified with three types ligands: Magnetite activated carbon (MAC), silica (tetraethoxysilane, TEOS, and 3-aminopropyltriethoxysilane, APTES) (MTA) silica, APTES humic acids (MTAH). MTAH sample shows greater porosity in comparison to MTA, MAC samples. band gap is 4.08 eV, which higher than MTA (2.92 e...

Luffa reinforced polylactic acid (PLA) bio-composites were prepared and examined. The luffa surface was treated using three chemicals, i.e., sodium hydroxide, 3-aminopropyltriethoxysilane, acetic anhydride, which enhanced compatibility with PLA. Mechanical testing done on the chemically modified PLA bio-composites, tensile, flexural, hardness, thermal. Infrared spectral functional group morphol...
