A Review Based on Spinel Ferrite Nanomaterials - MgFe2O4 - Synthesis of Photocatalytic Dye Degradation in Visible Light Response

Abstract

MgFe₂O₄ nanomaterials may indeed be generated using a multitude of approaches. The nanoparticles were used as a dye degradation catalyst. In the presence of H₂O₂, remarkable results demonstrate 100 % approx. deterioration at different timeframes. The Fenton process of hydroxyl and super hydroxyl radicals is responsible for the dye's rapid breakdown. Because the catalyst is superparamagnetic, it may be extracted from treated water using an external magnet. MgFe₂O₄ is a promising and efficient adsorbent for the removal of dye from wastewater. The photocatalyst that was produced here was very reusable and efficient by various methods such as Hydrothermal, microwave solution, solution combustion, green synthesis, Hammer’s, sol-gel method etc. The goal of this report is to investigate catalyst behaviour for the separation of Rb21 dye from wastewater in terms of structural, compositional, crystallinity, and magnetic stability. To test the reusability at a low catalyst dose in a concentrated dye solution, many runs are performed. In the future, the catalyst might be employed in a variety of applications, including catalyst, lithium-ion batteries, drug delivery, and magnetic transformer cores.
