In this study, a nanostructured CeVO4 material was synthesized using simple co-precipitation technique and investigated as catalyst for phenol degradation via peroxymonosulfate (PMS) activation. The structural morphological properties of the were characterized XRD, XPS, FTIR, Raman spectroscopy, TGA, SEM, TEM. results indicated that prepared exhibited pure crystalline phase with rod-like structure. high activity towards PMS activation, resulting in complete within first 80 min at room...
The ordered open organic frameworks membranes are attractive candidates for flow-assisted molecular separations. physicochemical properties of such mostly depend on their selectively chosen functional building blocks. In this work, we have introduced a novel concept switchability three-dimensional covalent framework (3D-COF) through simple solvent-influenced fragmentation method. This room-temperature interfacial synthesis provides free-standing 3D-COF with distinct from the same monomers....
Immobilization of enzymes on inorganic supports such as silica and carbon materials is an effective approach for chemical surface modification. In this work, hierarchical zeolite (HZ-SAPO's) were fabricated by a modified method, mesoporous (CMK-3) was synthesized using the SBA-15 template. A variety biocatalysts prepared HZ-SAPO with CMK to furnish nanocomposite biocatalyst. The functionalization amine group APTES done which further immobilized Soybean Peroxidase (SBP) enzyme. material...
A continuous electrocatalytic reactor offers a promising method for producing fuels and value-added chemicals via hydrogenation of biomass-derived compounds. However, such processes require better understanding the impact different types active electrodes reaction conditions on biomass conversion product selectivity. In this work, Ni1−xPdx (x = 0.25, 0.20, 0.15) alloyed nanostructures were synthesized as heterogeneous catalysts furfural. Various analytical tools, including XRD, SEM, EDS,...
CuFe2O4 nanoparticles were synthesized and immobilized on sepiolite fibers graphene oxide sheets, producing a CuFe2O4/sepiolite/GO (CFSG) nanocomposite via facile single-pot method. The was characterized using TEM, FTIR, SEM–EDX, XRD, TGA techniques to determine its composition, structure, thermal stability. adsorptive removal of Pb(II) Cd(II) heavy metal ions from aqueous solutions studied the CFSG nanocomposite. Adsorption parameters such as loading, pH, contact time, temperature...
Abstract Spinel ferrite nanoparticles can be easily retrieved and utilized for multiple cycles due to their magnetic properties. In this work, of a Zn x Cu 1-x Fe 2 O 4 composition were synthesized by employing sol–gel auto-combustion technique. The morphology, composition, crystal structure examined using scanning electron microscopy, infrared spectroscopy, X-ray diffraction. produced are in the range 30–70 nm manifest spinel cubic structure. tested sensitivity H S gases, Cu-based found...

Copper ferrite (CuFe 2 O 4 ) nanoparticles were prepared using the sol-gel autocombustion method and then coated with phosphate different treatments H 3 PO . The structural chemical properties of phosphate-coated CuFe controlled by changing concentration during coating process. characterized XRD, FTIR, SEM, EDS which provided information about catalysts’ structure, composition, purity, morphology. catalytic photocatalytic activities samples tested evaluated for degradation phenol HPLC....
Nowadays, cobalt-based catalysts are becoming increasingly attractive for various reactions. In this work, the catalytic and photocatalytic activities of different cobalt ferrites were investigated degradation phenol in water at neutral pH. Pure CoFe2O4 mixed CoxNi1-xFe2O4 synthesized using precursors (chloride nitrate). derived from chloride showed a higher efficiency compared to those nitrate precursors. Significant enhancement was observed when Ni incorporated into CoFe2O4. Furthermore,...
Organic pollutants such as 4-nitrophenol (4-NP) pose serious environmental extortions due to their chemical stability for which efficient catalytic materials are indispensable in treating them. In this regard, the present work involves synthesis of two different types ferrites (NiFe2O4, and CuFe2O4), a combination NixCuxFe2O4 with various ratios that systemically photocatalysts without any additional reducing agents is reported. The structural, morphological properties NiFe2O4, CuFe2O4,...
The environmentally friendly nature of natural cellulose, as well its excellent crystallinity and mechanical properties, have piqued researchers' interest. In this study, date palm seeds agricultural waste generated abundantly every year in the Gulf region were used a raw material to extract crystalline nanocellulose. Dewaxing, alkali treatment, bleaching, acid hydrolysis stepwise treatment approach remove nanocellulose from seeds. amorphous phase biopolymer had been successfully removed,...
