Effect of cobalt substitution on structural, elastic, magnetic and optical properties of zinc ferrite nanoparticles

The effect of Zn-doping in CoFe2O4 nanoparticles (NPs) through chemical co-precipitation route was investigated in term of structural, optical, and magnetic properties. Both XRD and FTIR analyses confirm the formation of cubic spinel phase, where the crystallite size changes with Zn content from 46 to 77 nm. The Scherrer method, Williamson-Hall (W-H) analysis, and size-strain plot method (SSPM) were used to study of crystallite sizes. The TEM results were in good agreement with the results of the SSP method. SEM observations reveal agglomeration of fine spherical-like particles. The optical band gap energy determined from diffuse reflectance spectroscopy (DRS) varies increases from 1.17 to 1.3 eV. Magnetization field loops reveal a ferromagnetic behavior with lower hysteresis loop for higher Zn content. The magnetic properties are remarkably influenced with Zn doping; saturation magnetization (Ms) increases then decreases while both coercivity (HC) and remanent magnetization (Mr) decrease continuously, which was associated with preferential site occupancy and the change in particle size.

Structural, Optical, and Magnetic Properties of Zn-Doped CoFe2O4 Nanoparticles.

Conventional and microwave combustion synthesis of optomagnetic CuFe 2 O 4 nanoparticles for hyperthermia studies

Pressure and osmotically driven membrane processes: A review of the benefits and production of nano-enhanced membranes for desalination

The widespread of organic and inorganic pollutants in wastewater from various industries, are responsible for serious environmental problems meanwhile represent a danger for human being. Therefore, the search of cost-effective methods of wastewater treatment containing in particular heavy metals and dyes, become of great importance. Noteworthy, adsorption has proven to be most effective technology for purification of wastewater from organic and inorganic pollutants. In this review, different types of green and ecofriendly materials (biosorbents, graphene-based composites, metal oxides, etc.) for dyes and heavy metals adsorption will be discussed. The biosorbents such as agricultural waste materials (waste seeds, orange peel, exhausted coffee ground powder, wood apple shell, sweet potato peels, wheat straws, etc.), activated carbon prepared from different types of agricultural waste (coconut husk, forest and wood-processing residues, papaya seeds, magnetic biochar etc.), graphene-based adsorbents and their derivatives, obtained by eco-friendly green synthesis, have been discussed and their adsorption activity has been described in details.
