Magnetism-driven iron oxide nanocomposites for energy and environmental solutions: harnessing magnetism

Magnetic iron oxide nanocomposites (MIO-NCs) have garnered considerable interest in both basic scientific research and emerging technological applications. MIO-NCs possess a paramagnetic nature that enables easy recovery of catalysts, thus enhancing their remarkable properties. In this overview, we detailed the synthesis methods of various MIO-NCs, with a particular focus on the nanocomposites of MIOs/polymers, MIOs/clay, MiOs/metal oxide, and MIOs/carbon materials. Owing to their unique properties, MIO-NCs have been explored for a vast range of energy and environmental applications in fields such as energy storage/generation, petroleum industry, adsorption process, and degradation of waste materials. These applications are significantly influenced by the size and morphology of NCs, which in turn are determined by the mode of synthesis. Given their established literature and significant commercial applications, MIO-NCs can be considered a broad class of modern materials for artificial intelligence and other emerging technological applications.
