Amine functionalized graphene oxide (NH2-GO) decorated with ZnO-ZnFe2O4 nanomaterials (NH2-GO/ZnO-ZnFe2O4) was successfully synthesized by organic transformation reaction followed hydrothermal method. The formation, composition, bonding, size, morphology, and surface area of nanomaterial were analyzed XRD, FTIR, Raman, XPS, FESEM, HRTEM, BET analytical techniques. formation binary phase onto the amine GO confirmed XRD HRTEM. composition functionalization prepared nanocomposite XPS FTIR...
In this study, we have synthesized alumina nanofibers by using an electrospinning method. The obtained were used as adsorbents for the removal of chromium(VI) and fluoride ions from aqueous system. morphology size characterized scanning electron microscopy transmission analytical techniques. X-ray diffraction study indicated formation pure crystalline α-alumina. effects pH, adsorbent dose, contact time, initial concentration adsorbate on nanofiber surface been studied. optimum pH values...
Iron oxide nanoparticles grown on the surface of an electrospun PAN nanofiber membrane can be used as a next generation nanoadsorbent for effective removal CR dye.
4-Nitrophenol (4-NP) is a high-priority industrial pollutant and known to cause adverse effects the human body. Owing this, detoxification of water contaminated with 4-NP highly essential. The photocatalytic degradation considered an efficient method. However, for this purpose, mostly expensive reagents that can on environment are used. Therefore, treatment water, eco-friendly method considerably required. To meet requirement, here, we have synthesized nitrogen-doped reduced graphene oxide...
The photocatalytic degradation of economically hazardous compounds has been thoroughly researched with the aid numerous photocatalysts and techniques. efficient removal lingering contaminants from aquatic environment are still difficult to accomplish. Hereby, we present a sulfur-doped reduced graphene oxide (SrGO) enwrapped magnetic porous nickel ferrite (NiFe2O4)/copper sulfide (CuS) nanocatalyst (SrGO/NiFe2O4/CuS:GNFC) constructed through facile solvothermal-reflux route. Under exposure...
Abstract We have successfully synthesized polyacrylonitrile (PAN) nanofibers impregnated with Ag nanoparticles by electrospinning method at room temperature. Briefly, the PAN‐Ag composite were prepared PAN (10% w / v ) in dimethyl formamide (DMF) solvent containing silver nitrate (AgNO 3 amounts of 8% weight PAN. The ions reduced into particles three different methods i.e., refluxing solution before electrospinning, treating sodium borohydride (NaBH 4 ), as reducing agent, and heating 160°C....
Fe<sub>2</sub>O<sub>3</sub>/ZnFe<sub>2</sub>O<sub>4</sub>/ZnO nanocomposites exhibit enhanced photocatalytic activity due to the cascade electron transfer from ZnFe<sub>2</sub>O<sub>4</sub> ZnO Fe<sub>2</sub>O<sub>3</sub>.
In this work, we have prepared polyacrylonitrile (PAN) polymer nanofibers by electrospinning method. The surface of the electrospun PAN membrane has been functionalized with ZnO-Ag heterostructure nanoparticles using three different chemical pathways such as reflux, blending, hydrothermal methods and accordingly composite membranes were named PAN/ZnO-Ag (R), (B) (H) respectively. obtained characterized ATR-FTIR, XRD, FESEM TEM analytical techniques. From images it was clearly observed that...
Contamination of surface water by extremely poisonous arsenic (As) species due to indiscriminant disposal industrial and mining waste is a serious concern worldwide. Considering the above apprehension, maghemite (γ-Fe2O3) graphene oxide (GO) embedded in polyacrylonitrile (PAN) polymer nanofiber matrix (PAN/GO/γ-Fe2O3) was successfully fabricated electrospinning technique. Successful incorporation γ-Fe2O3 GO into PAN via process investigated Fourier transform infrared (FTIR) spectroscopy,...
