Iranian Chemical Science and Technologies Association International Journal of New Chemistry 2645-7237 12 3 2025 03 01 An overview on recent trends of spinel ferrites (MFe2O4: M= Fe2+, Co2+, Mn2+, Ni2+, Zn2+) synthesis and catalytic applications 283 317 713907 10.22034/ijnc.2024.2032437.1398 EN Vidya Singh Maharana Pratap Govt P G College 0009-0006-9679-7166 Journal Article 2024 06 14 The synthesis of efficient catalysts is a key strategy for addressing the environmental and energy problems. Catalytic research has focused a lot of interest on spinel ferrites, which have a chemical formula of MFe2O4 (M = Fe2+, Co2+, Mn2+, Ni2+, Zn2+ etc). A multitude of surface-active sites, high catalytic activity and ease of modification are only a few of the many physicochemical characteristics of spinel ferrites, which are caused by the metal cations changeable location and valence flexibility. Meanwhile, their special benefits in recycling and regeneration because of their magnetic characteristics promote their practical use potential. This article examines how spinel ferrites are made utilizing conventional and environmentally friendly chemical processes. Most significantly, a thorough review of the major pathways, mostly connected to selective doping, site replacement, structural reversal, defect introduction and linked composites is provided in order to enhance catalytic performance. A review is also given to the many catalytic uses of spinel ferrites and the composites they produce, such as Fenton-type catalysis, photocatalysis, electrocatalysis, and photo-electro-chemical catalysis. Important factors including recovery, reuse, and toxicity are also addressed. It is anticipated that spinel ferrites will be utilized in energy and environmental applications in the future. These applications will be driven by the development of expert modification, accurate synthesis, complex characterization, and theoretical calculations. https://www.ijnc.ir/article_713907_b1f1b17aeee70f2e3a8a5f1be9185483.pdf
