The present work shows the photocatalytic degradation of nitrobenzene (NB) using Fe3O4 magnetic nanoparticles (MNP) as a photocatalyst in presence UV light. MNP were synthesized by an ultrasonic-assisted reverse co-precipitation (US-RP) method FeSO4, FeCl3 and NH4OH precursors. prepared characterized UV–vis spectroscopy, attenuated total reflectance Fourier transformed infrared spectroscopy (ATR FT-IR), Raman X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM),...
In this work, five new chelating resins (MRnBz) functionalized with N -benzyl bis(carbamoyl)carboxylic acid molecules (Bz bCCA ) on their surface were prepared to study the metal ion (M n + adsorption properties in water.
Solid polymer electrolytes (SPEs) are gaining attention as viable alternatives to traditional aqueous in zinc–air batteries (ZABs), owing their enhanced performance and stability. In this study, anion-exchange solid (A-SPEs) were synthesized via electrophilic aromatic substitution reactions. Thin films prepared using the solvent casting method characterized proton nuclear magnetic resonance (¹H-NMR), Fourier-transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA). The...
The contamination of both soil and water by nitrobenzene (NB) is a problem that has been studied, where several reactive agents have developed for the degradation this compound as well different methods. Nanoparticles with semiconductive properties studied organic compounds photodegradation due to their assistance in optimizing processes. Two most promising photocatalysts are ZnO TiO2 because optimal results. In present work performance zinc peroxide (ZnO2) nanoparticles was evaluated. ZnO2...
Photocatalysis is a method widely used in the degradation of organic pollutants environment. The development new materials very important to improve photocatalytic properties and find applications for TiO2 as photocatalyst. In this article we reported synthesis photocatalyst based on doped with Zn2+ ions highly efficient nitrobenzene. results activity experiments showed that more active than un-doped catalyst an efficiency 99% nitrobenzene at 120 min apparent rate constant 35 × 10-3 min-1.
Abstract. Four thin-film composite (TFC) polyamide negatively charged nanofiltration (NF) membranes (NF-PS-1, NF-PS-2, NF-PS-3 and NF-PS-4) were prepared via interfacial polymerization technique which involved the formation of a thin film at polysulfone (PS) microporous substrate between two immiscible liquid phases; an aqueous phase containing piperazine organic trimesoyl chloride (TMC = 0.25, 0.50, 1.00 2.00 wt%). Correlations intrinsic properties these four NF filtration membranes, in...
In the present work, chemically modified graphene oxide (GO) was incorporated as a crosslinking agent into thin-film composite (TFC) nanofiltration (NF) membranes for water desalination applications, which were prepared by interfacial polymerization (IP) method, where monomers piperazine (PIP) and trimesoyl chloride (TMC). GO functionalized with monomer-containing groups to promote covalent interactions polymeric film. The GO/polyamide (PA) incorporating amine acyl structure of then adding...
A Gamma irradiation and photochemical crosslinking/grafting of poly(2-hydroxyethyl methacrylate) (PHEMA) methacrylate-co-poly(ethylene glycol) (poly(HEMA-co-PEGMA)) hydrogels onto polyethyleneterephtalate fabric (PET) surfaces were evaluated, in order to obtain a hydrophilic homogeneous coating PET fabrics.

Research has focused on biomass as a sustainable energy source, driving valorization to convert carbohydrates. The price of lactose dropped below the production cost, urging exploration for diverse applications, such conversion into value-added compounds. Zeolites, especially Y zeolite, enhance hexose when modified with metals. Fe-modified zeolites show promise, controlled Si/Al ratios impacting acidity and selectivity. recent challenges remain in active site comprehension, catalyst...
The effect of the nature catalyst on performance and mechanism hydrogen oxidation reaction (HOR) is discussed for first time in this work. HOR an anodic that takes place anionic exchange membrane fuel cells (AEMFCs) pumps (HPs). Among investigated catalysts, Pt exhibited best HOR. However, cost availability limit usage. Co incorporated as a co-catalyst due to its oxophylic nature. Five different PtCo catalysts with loading values were synthesized order decrease loading. catalytic activities...
Polysulfone (PSF) and smart polymers (SRPs)—including polyacrylic acid (AAc), poly N-isopropylacrylamide (NIPA), sulfonated poly(1,4-phenylene ether-ether-sulfone) (SPEES)—were used in the synthesis of responsive membranes (PSF-SRP) for application sustainable desalination processes involving food industry effluents water recovery recycling.
