A critical review on nano ferrites pioneering a paradigm shift in corrosion inhibition towards different metal/alloys in diverse corrosive environments

The recent scenarios in the realm of metals and their associated implications in varied industrial sectors calls for the extensive exploration of the prevalent issue of corrosion, its economic implications, and inhibition techniques. Nano ferrites (NFs) in this regard have been seen emerged as highly promising corrosion inhibitors, addressing the challenges imposed by conventional inhibitors as well as perceived aligning with the goals of green and sustainable technologies. Highlighting the significance of nanostructured materials, the review specifically focuses on NFs, detailing their structural and chemical attributes, including high surface area along with extraordinary chemical and thermal stabilities which contribute to their effectiveness as corrosion inhibitors. The synthesis methods of NFs have been critically examined particularly those allowing for a controlled precision over particle size as well as composition. Additionally, the review explores various surface modification strategies aimed at improving their interaction with metal surfaces, resulting in genesis of robust protective films and passivation layers. A thorough literature review has been included highlighting the deployment of varied NFs as corrosion inhibitors across diverse environments. Their associated advantages and limitations as corrosion inhibitors have also been generously reviewed, providing a comprehensive overview of these materials as corrosion inhibitors. Additionally, the work concludes with a discussion on future perspectives, emphasizing the need for innovative synthesis techniques, advanced characterization methods and interdisciplinary collaboration to fully harness the potential of NFs in corrosion inhibition.
