WebThe characteristics of ZnFe2O4 were investigated using Fourier transform infrared (FTIR), X-ray diffraction (XRD) and scanning electron microscope (SEM). Photocatalytic dye degradation by ZnFe2O4 was studied by UV-vis spectrophotometer and ion chromatography (IC). The effects of ZnFe2O4 dosage, initial dye concentration and salt on dye ... WebZnFe2O4 sample was then examined using FTIR spectroscopy to identify the functional group of ZnFe2O4, with calcination temperatures varying between 500 o C, 600 o C, and 700 o C. ZnFe2O4 FTIR ...

WebDec 15, 2013 · Superparamagnetic zinc ferrite (ZnFe2O4) nanoparticles were prepared by a surfactant assisted hydrothermal method and subjected to the heat treatment. The structure, vibrational, morphology, and magnetic properties of synthesized product were characterized by XRD, FT-IR, HR-SEM, and VSM measurements. XRD result confirms the formation of … WebThe physical and chemical properties of ZnFe2O4@SiO2‐ascorbic acid were considered by XRD, FT‐IR, TGA, SEM, EDS, and vibrating sample magnetometer (VSM) analyses. WebThe Raman frequency depends on the Fe (Zn)-O bond length, which changes with the lattice parameter variation and particle size [16, 47]. Conversely, the spectrum of CuFe 2 O 4 NPs shows five ... he359rtd100
