Characterization of NiFe2O4 (Nickel Ferrite) nanoparticles with very low magnetic saturation synthesized via co-precipitation method

Synthesis and characterization of NiFe2 O4 nanoparticles by tartaric acid assisted sol-gel auto-combustion method

“…Table 1 summarizes the computed structural parameters. The reported results agree well with the literature values [1,12]. 14.00 δ (nm -2 ) 0.0051 ρ x (gm/cc) 5.420…”

“…Further, the as-prepared Nickel ferrite sample was calcined at 600 ˚C for 2 hr. Thus, the weight loss up to 600 ˚C indicates oxidation of metal ions and formation of ferrite phase [1,3], which was confirmed by XRD, FTIR analysis and are shown in figures 1(b) and (d), respectively.…”

“…In NiFe 2 O 4 , Ni 2+ ions will be distributed among available O h -sites and Fe 3+ ions will be evenly distributed among both T d -and O h -sites. In recent years, preparation of ferrite nanoparticles with different preparation conditions and their effects on structure and morphology has been explored [1][2][3][4]. In order to produce stoichiometric and chemically pure spinel ferrite nanoparticles, widely used chemical methods, such as hydrothermal [5], microwave combustion [2], combustion [3], co-precipitation [1] and sol-gel technique [6] have been developed.…”

Because of its simple preparation procedure, easy to manage stoichiometry, good chemical homogeneity, high purity and crystallinity with minimal processing time, the sol-gel combustion method is one of the most often utilized synthesis approaches [7].…”

Metal oxide/chitosan composite for organic pollutants removal: A comprehensive review with bibliometric analysis

“…Magnetic metal oxides have a cube crystal structure that comes in various shapes and sizes [42]. The crystal structure differs depending on the type of metal used, for example NiFe2O4 has a spinel structure [43], and MnFe2O4 has a cube structure [44]. Each structure has a different density, magnetization, and coercivity.…”
