Abstract
About this talk
Mg0.8Zn0.2-xCuxFe2O4; (step 0.04) (MZC) nanoferrites were prepared by the citrate combustion method. Adequate amount of zinc nitrate, magne- sium nitrate, ferric nitrate and copper nitrate were resolved in minimal distilled water and then soni- cated for 10 min at room temperature unto a dia- phanous solution was obtained.
The dielectric constant and conductivity of MZC nanoferrite manifested the higher values than the pristine one. This leveraging demeanor is originated from the effective role of Fe2 and Fe3 in octahedral sites; as a result of occupying Cu ions in tetrahedral sites only. All MZC nanoferrites have the two types of losses; conduction and relaxation losses. The conduction process of MZC nanoferrites is attributed to three different species through different temperature ranges.
The nanoferrite Mg0.8Cu0.2Fe2O4 has the highest e0 and rac, moderate loss, lowest band gap and highest photocatalytic activity for RhB removal. All these advantages make it an auspicious candidate for electronic applications (especially for high- frequency applications and transformers cores) and wastewater treatment process .
