Visible light photocatalytic activity of magnetically diluted Ni–Zn spinel ferrite for active degradation of rhodamine B

Effect of Cu doping on structural and magnetic properties of Cu x Zn1-x Fe2O4 nanoparticles for biomedical applications

“…at 407 cm −1 shows the formation of cation oxygen bond at octahedral site and the second band (γ 1 ) at 530 cm −1 shows the formation of metallic ion oxygen bond at tetrahedral site. From FTIR, one confirms the spinel structure of ferrite nanoparticles[15][16][17][18]. The γ 1 band moves into the lower frequency side as the Zn ions replaced by Cu ions preferably possess those A sites and Cu ions now occupy these sites and that difference in the ionic radius of A site cations (Fe 3+ and Zn 2+ ) is much larger than that of B site cations (Fe 3+ and Cu 2+ ).…”

“…Using this method, size and shape of obtained ferrite can be engineered by changing annealing temperature and synthesis condition. In the present work, Cu-Zn ferrite samples are studied to view their structural and magnetic behaviour with antibacterial and antifungal properties [13][14][15][16][17][18].…”

Engineered magnetic oxides nanoparticles as efficient sorbents for wastewater remediation: a review

“…Swapnil A.Jadhav and his colleagues (Jadhav et al 2021) prepared Zn x Ni 1-x Fe 2 O 4 (0.0 ≤ x ≤ 1) utilizing urea as fuel. The X-ray diffraction pattern indicated the generation of cubic structure with the Fd-3 m space group.…”

“…Besides, the accumulation decreased by increasing the quantity of Ni-Zn. The Ni 0.5 Zn 0.5 Fe 2 O 4 nanoparticles manifested the highest photocatalytic degradation of rhodamine B owing to their smaller crystalline size (Jadhav et al 2021). Milena P. Dojcinovic et al (Dojcinovic et al 2021) synthesized Co x Mg 1-x Fe 2 O 4 utilizing citric acid as fuel and tested them for photocatalytic removal of Methylene Blue.…”

“…Also, (Jadhav et al 2021) produced Ni-Zn spinel ferrite using urea as a fuel in the sol-gel auto combustion process. They evaluated the produced samples for the elimination of Rhodamine B from the industrial wastewater.…”
