Spinel ferrites are a family of elements that possess remarkable stability, magnetic characteristics, and photocatalytic efficacy due to their unique cubic crystal structure. Figure from the Scopus database provides proof that spinel ferrites have been employed for the past 13 years. The statistics of publications indicate that there have been 11,751 publications on spinel ferrites in the past 13 years. Over time, a growing body of research on spinel ferrites was carried out. They consist of trivalent (octahedral) and divalent (tetrahedral) metal cations, which are represented by the general formula AB2O4 in Figure . The photocatalytic behaviour of these cations is significantly influenced by the presence of transition metals. These metals cause the bandgap to become concentrated in electronic states, which effectively separates charges, which is an essential part of photocatalysis. The remarkable properties of spinel ferrites such as their remarkable chemical stability, low bandgap energy, and ability to generate hydroxyl radicals in response to light have drawn a lot of attention. These qualities provide great promise for water restoration procedures and make them perfect for the effective degradation of organic contaminants. Their ability to separate easily from the reaction liquid is due to their magnetic characteristics, which improve process efficiency and lower secondary pollutants. We present a comprehensive overview of the latest advancements in spinel ferrite-based photocatalysts in this work. We study synthesis methods that significantly affect ferrites' size, shape, and surface properties, all of which affect how well they photocatalyze. We also look at doping schemes and changes that improve their photocatalytic activity, such as heterojunction creation and bandgap engineering. Furthermore, we use spinel ferrites to study the processes behind the photocatalytic degradation of contaminants. We focus on the role played by reactive oxygen species (ROS) and charge carrier separation and transfer mechanisms. We also investigate the effects of various operating parameters on the photocatalytic process, including pH, temperature, light intensity, and catalyst dosage. Lastly, we draw attention to the difficulties and constraints that still exist in the real-world use of spinel ferrites for the remediation of water pollution, including issues with reusability, long-term stability, and scaling up the photocatalytic process for commercial uses. We wrap up by talking about potential avenues for future studies, such as investigating new composite materials, exploring unexplored spinel ferrite systems, and incorporating these materials into cutting-edge water treatment technologies. According to this review, spinel ferrites hold a great deal of promise as adaptable materials to fight water pollution. The present study aims to provide an overview of the potential, difficulties, and state-of-the-art related to the use of these materials in advanced material science and environmental sustainability. Figure The diagram mentioned above illustrates the structure of spinel ferrites which is depicted with distinct colours representing oxygen atoms (depicted in red), tetrahedral sites (depicted in yellow), and octahedral sites (depicted in blue).
