CuFe₂O₄ nanomaterials: Current discoveries in synthesis, catalytic efficiency in coupling reactions, and their environmental applications

Abstract

In the last few decades, there has been enormous growth in ferrite nanoparticles. Magnetic, optical, and electrical properties of ferrites gain consideration due to their use in various applications such as rechargeable lithium batteries, medical diagnostics, solar energy devices, and so forth. A vast increase in interest in ferrite nanoparticles has led them to be used as catalysts in various applications as they possess a large surface area‐to‐volume ratio. Furthermore, iron‐based magnetic characteristics make it simple to retrieve catalysts by using an external magnet. Iron's catalytic potential, however, is far less than copper's. Therefore, the catalytic scope is substantially increased by substituting copper within the crystal lattice. Recently copper ferrite nanoparticles have caught the interest of numerous researchers due to low‐cost magnetic material, stability under diverse conditions, and ease at which catalyst can be retrieved using an external magnetic field and utilized repeatedly. This review of data from year 2010 through 2022 emphasizes the synthesis method, structure, application in dyes degradation, catalytic potential in the number of coupling reactions, recyclability, and reusability of the magnetic catalyst.

“…In spite of these benefits, the utilization of such small particles is constrained by the need for time‐consuming reuse and expensive ultracentrifugation for separation. Magnetically separable nanoparticles, such as ferrites and other doped metal ferrites, offer a variety of uses in industrial and organocatalytic processes to solve these issues by increasing reusability and recyclability 16 . Fe 2 O 3 and Fe 3 O 4 nanoparticles mainly provide extensively researched essential magnetic assistance in this regard because of their giant catalyst loading ability, significant surface area, resistivity, magnetization, catalytic performance, as well as impact strength 17 .…”
