The effect of fuel on the physiochemical properties of ZnFe2O4 synthesized by solution combustion method

Abstract

The synthesis of ZnFe 2 O 4 nanoparticles was performed using the solution combustion method with three types of fuel, namely urea, glycine, and ethylenediamine tetra-acetic acid (EDTA) with precursors (Zn(NO 3 ) 2 .6H 2 O and Fe(NO 3 ) 3 .9H 2 O. The combustion process was conducted in an open space at 300 °C for ± 1 h, resulting in a brownish-black ZnFe 2 O 4 . Meanwhile, the fuel type used in the process affects the physicochemical properties of ZnFe 2 O 4 . XRD analysis showed that ZnFe 2 O 4 synthesized using urea, glycine, and EDTA had spinel structures with crystal sizes of 10.19, 20.34, and 27.21 nm, respectively. The FTIR spectra of ZnFe 2 O 4 synthesized using the three fuel types had Zn-O and Fe-O stretching vibrations. Furthermore, the morphology of ZnFe 2 O 4 synthesized using urea was more homogeneous than glycine and EDTA. The saturation magnetization of ZnFe 2 O 4 synthesized using EDTA was 54.63 emu/g compared to glycine and urea, 50.93 and 44.73 emu/g, respectively. Finally, the surface area of synthesized ZnFe 2 O 4 using urea, glycine, and EDTA were 116.4, 100.6, and 94.2 m 2 /g, respectively.

Optimizing the synthesis of ZnFe2O4 through chemical and physical methods: effects of the synthesis route on the phase purity, inversion, and magnetic properties of spinel zinc ferrite

“…The absorption bands at 3440 cm −1 and 1631 cm −1 are assigned to the O H -stretching and d H O H ( --)bending vibrational modes of water, respectively [46][47][48][49], whereas the band at 2360 cm −1 is assigned to the = = O C Ostretching mode of CO 2 [47]. On the other hand, the band at 542 cm −1 is associated with the vibrational mode of the Zn-O bond in tetrahedral sites, which is consistent with the reported values [50,51]. The red arrow marks a shoulder at about 670 cm −1 which indicates the splitting of the tetrahedral band [52].…”

Reusing blended leach residue by flash sintering method

Structural, magnetic and electrochemical studies on ZnxMg1-xFe2O4 nanoparticles prepared via solution combustion method

“…Presently, numerous methods exist for synthesizing nanopowders of multicomponent zinc-magnesium ferrites [13], including hydrothermal synthesis [14], sonochemical synthesis [15], co-precipitation method, various types of solution combustion methods [16], synthesis in activator mills [17] and sol-gel technology [18]. Notably, the solution combustion method has garnered attention due to its simplicity, cost-effectiveness, and potential for industrial scalability, offering a pathway to volumetric yields akin to classical solid-phase techniques [19]. Recent efforts within this method have seen the synthesis of zinc-magnesium ferrites employing citric acid and microwave treatment [20,21].…”
