MCM-41 and Zn-MCM-41 were successfully synthesized using hydrothermal impregnation methods. The silica mesoporous was confirmed by characterizing the material XRD, SEM-EDS, BET-BJH analyses. XRD results showed three main peaks at angles of 2θ = 2.40° (100), 3.87° (200), 4.49° (210), which are characteristics materials with hexagonal structures. SEM analysis that surface morphology Zn-modified f...

A novel catalyst based on g-C3N4/activated carbon was prepared by adding CuCl2. The catalytic performance of the as-prepared catalyst was investigated in the acetylene hydrochlorination reaction. X-ray photoelectron spectroscopy, temperature programmed desorption, low temperature N2 adsorption/desorption (Brunauer–Emmett–Teller), and thermal gravity analysis showed that Cu-g-C3N4/AC significant...

The aim of this study was to produce a low-cost activated carbon (AC) from an inexpensive precursor material, corn stigmata (CS), by chemical activation at low temperatures using H3PO4, ZnCl2 and KOH. results were showed that with phosphoric acid provides adsorbent larger specific surface area (SBET) high pore size. Textural physicochemical properties ACs H3PO4 then studied in different tempera...

In this research, a simple oxidation chemical process was applied for the synthesis of novel PANI@ZnO nanocomposite. The prepared nanocomposites were characterized by XPS, XRD, FTIR, SEM, TGA and N2 adsorption–desorption isotherms. Thereby, highest SBET values (about 40.84 m2 g?1), total mesoporous volume 3.214 cm3 g?1) average pore size 46.12 nm). Afterwards, nanomaterial as nanoadsorbent adso...

A functionalized nylon6/polypyrrole core-shell nanofibers mat (PA6/PPy NFM) was prepared via situ polymerization on nylon6 electrospun nanofibers mat (PA6 NFM) template and used as an adsorbent to remove atrazine from aqueous solutions. The core-shell structure of PA6/PPy NFM can be clearly proved under scanning electron microscope (SEM), transmission electron microscopy (TEM), and X-ray photoe...

Mixed metal oxide composites have been widely used as adsorbents for the removal of heavy ions from wastewater. In this work, Fe2O3/TiO2 composite was sustainably prepared via treatment titanium slag with a low-concentration sulfuric acid solution (20%) and As(V) aqueous solutions. The resulting products were characterized by X-ray diffraction (XRD), N2 adsorption−desorption, Fourier-transform ...

Polyaniline/cerium oxide (PANI/CeO2) composites were prepared and characterized by XRD, FT-IR, nitrogen adsorption/desorption isotherms and TEM techniques. The PANI/CeO2 composites were used for removal of Remazol Red (RB-133) from aqueous solution. The adsorption behaviour of dye was studied at different experimental conditions of solution pH and reaction temperature. The adsorption isotherm s...

In this study, bimodal meso-porous silica (UVM-7) synthesized and fabricated amino silane modified supports were characterized by powder X-ray diffraction (XRD), N2 adsorption/desorption, transmission electron microscope (TEM), elemental analysis and titration. Capacity of CO2 capture on modified bimodal pore structure silica at 70°C was calculated using breakthrough curves; and it was found th...

This study was conducted to investigate the influence of the saturating cation on the adsorption of parathion, methyl parathion, fenitrothion, aminoparathion, and paraoxon by montmorillonite suspensions. In all cases the saturating cation distinctly influenced the Freundlich-type adsorption, with adsorption decreasing in the following sequence: Fe—> Ca— > Na-montmorillonite. Adsorption of parat...

Mesoporous tungstic acid functionalized KIT-6 has been synthesized through a condensation of (3-chloropropyl) triethoxysilane and Si-KIT-6 followed by substitution of chloromethylation functionalized KIT-6 by sodium tungstate dihydrate. The synthesized tungstic acid functionalized KIT-6 (W-KIT-6) was characterized by low and wide angle X-ray diffraction analysis (XRD), N2 adsorption-desorption ...
