Copper and Copper-Based Nanoparticles for Water Treatment

Abstract

Copper nanoparticles (CuNPs) nanoparticles have garnered significant attention in recent years due to their unique physicochemical properties, including high surface area, quantum effects, and size-dependent optical, electrical, and catalytic characteristics. Cu NPs are valued for their catalytic efficiency in oxidation and reduction reactions, enhanced by their large surface area. Their cost-effectiveness compared to other noble metals like gold and silver makes them a viable choice for industrial applications. However, challenges such as agglomeration and stability remain, necessitating the use of support materials like alumina, graphene oxide, and titanium dioxide to improve their durability and performance. This review explores the synthesis methods of Cu NPs, highlights their applications in water treatment using advanced Cu-based nanoparticles. The synergy between copper and various support materials enhances catalytic performance and offers promising solutions for environmental challenges.
