A Review on Green Synthesis of Magnetic Nanoparticles: Unlocking Catalytic Potential for Environmental Sustainability

Abstract

Eco-friendly nanomaterials have garnered a lot of attention recently because of their long-term benefits across a range of industrial domains. Traditional techniques for creating nanoparticles frequently require a lot of energy and hazardous chemicals, both of which pollute the environment. The primary objective of this work is on recent developments in the environmentally friendly synthesis of magnetic nanoparticles, particularly those made of iron oxide (FeO), copper oxide (CuO), and nickel oxide (NiO). By utilizing natural resources including plant extracts, microorganisms, and agricultural waste, green synthesis provides an alternate technique. This technique enhances the nanoparticles' catalytic activity while simultaneously promoting environmental safety. Their significance in sustainable technologies is emphasized in this review, particularly in applications like as pollution control, redox processes, and carbon dioxide reduction. The synthesis methods, catalytic efficiency and environmental relevance of these green-synthesized nanoparticles are discussed. Such approaches support sustainable nanotechnology. The knowledge about green synthesis methods is vital for producing efficient and safer nanomaterials. As industries shift towards eco-conscious production, these materials may find wide application in future technologies.
