Advances in Magnetic Spinel Ferrites as photocatalysts for waste water treatment: A Review

Abstract:

This review highlights the recent advancements in the synthesis and application of magnetic spinel ferrites (SFs) for wastewater treatment, focusing on their photocatalytic and adsorptive properties. SF nanoparticles, with unique characteristics such as high surface area, tunable magnetic properties, and chemical stability, offer efficient pollutant degradation and recovery via magnetic separation. Various synthesis techniques, including sol-gel, hydrothermal, and solution combustion, have been explored to enhance their morphology, porosity, and catalytic efficiency. SFs demonstrate exceptional performance in degrading organic pollutants, dyes, and pharmaceutical contaminants under visible light, leveraging their photocatalytic and adsorption mechanisms. The effectiveness is further increased by combining SFs with advanced materials including g-C3N4 and r-GO. A worldwide sustainable water treatment issue makes this study significant because SFs present scalable environmentally friendly solutions that have revolutionary potential.
