First, crystalline NiFe2O4 powder was synthesized on a nanoscale dimension by a simple one-step coprecipitationchemical route, and then used to produce activated carbon/NiFe2O4 nanocomposite. Thestructure and morphology of the as-prepared composite was characterized by X-ray diffraction (XRD)pattern, transmission electron microscope (TEM) and Fourier transform infrared (FT-IR)...

In this study, a nickel ferrite (NiFe2O4) system was constructed to purify phenol solution in water. During the process, influences of several critical operating parameters including NiFe2O4 amount, PS dosage, MW power, initial pH value, and different natural water anions were systematically studied. The results indicated that performed excellently regarding removal efficiency (97.74%) within 3...

Escalating energy demands, scarcity of conventional resources and environmental concerns are the key to fuel production through water splitting. Various electrocatalysts have been reported, considering cost effectiveness, stability OER (oxygen evolution reaction) activity. In same context, porous hybrid NiO-NiFe2O4/MWCNTs based nanocomposite as an electrocatalyst, has investigated in current st...

A hollow hybrid Ni-Fe-O nanomaterial (NiFe2O4) is synthesized using a precursor of metal-organic frameworks through a simple and cost-effective method. The unique hollow nanocage structures shorten the length of Li-ion diffusion. The hollow structure offers a sufficient void space, which sufficiently alleviates the mechanical stress caused by volume change. Besides, the hybrid elements allow th...

Pb(Zr,Ti)O3–NiFe2O4 thin-film composites were fabricated by spin coating a nickel ferrite precursor solution onto self-assembled porous lead zirconate titanate thin films. The morphology investigations revealed very extensive interface area between both constitutents. X-ray diffraction shows that NiFe2O4 coatings induce large compressive in-plane stresses in Pb(Zr,Ti)O3, which are generated dur...

Nickel ferrite (NiFe2O4) thin films are grown epitaxially on two different isostructural substrates, (100)-oriented MgGa2O4 and ZnGa2O4, using pulsed laser deposition. These spinel substrates have a lattice mismatch of 0.62% 0.04%, respectively, with NiFe2O4 crystal. While the exhibit significant strain resulting in tetragonal distortion crystal structure, ZnGa2O4 substrate essentially strain-f...

Nano-sized NiFe2O4 powders were synthesized by sol–gel auto-combustion method using pH values from 7 to 9 in the sol. The effect of pH variations on complexing behavior of the species in the sol has been explained. Changes in phase constituents, microstructure and magnetic properties by changes in pH values were evaluated by X-ray diffraction (XRD), field emission scanning electron micros...
