Progress in the Preparation and Modification of Zinc Ferrites Used for the Photocatalytic Degradation of Organic Pollutants

“…Sonia et al [ 63 ] found that ZnFe 2 O 4 prepared using the sol-gel method had better homogeneity but slightly lower stability when compared to the material prepared via the co-precipitation technique. Prasad et al [ 64 ] used citrate gel to synthesize ZnFe 2 O 4 with an average size of 22 nm and saturation magnetization value of 12.87 emu/g. Kumar et al [ 65 ] studied the effect of the calcination temperature on the material properties; an increase in the calcination temperature from 550 to 900 °C led to a decrease in the saturation magnetization value from 6.84 to 4.26 emu/g.…”

Magnetic, structural and cation distribution studies on $\mathrm{FeO}\cdot\mathrm{Fe}_{(2-x)}\mathrm{Nd}_{x} \mathrm{O_{3}}$ (x = 0.00, 0.02, 0.04, 0.06 and 0.1) nanoparticles

“…position that correspond to origin at A-site, the value of u ideal is expected to be 0.375. Therefore, changes in the value of u can be interpreted as a relaxation of the structure to accommodate the cations of different radius in the A and B sites [30,47]. The jump (hopping) lengths, L A and L B between the magnetic ions at A-site and B-site respectively, were calculated (Table III).…”
