This review discusses the modification of reverse osmosis (RO) membranes using nanomaterials to enhance their performance and lifespan. Traditional RO membranes face challenges such as fouling, reduced salt rejection, and low water flux. Nanomaterials, including metal oxides, zeolites, and carbon-based materials, have been extensively studied for their potential to improve membrane properties. The review covers the synthesis methods, integration techniques, and impacts of nanomaterials on RO membrane performance. It highlights the mechanisms behind improvements, such as increased hydrophilicity, reduced fouling, and enhanced structural stability. Challenges and limitations of using nanomaterials in RO membranes are also analyzed. The review emphasizes the benefits, challenges, and future prospects of nanomaterial-modified RO membranes, providing a comprehensive understanding of their potential in water treatment applications. Key findings include the effectiveness of graphene oxide (GO) and carbon nanotubes (CNTs) in enhancing water flux, reducing fouling, and improving chlorine resistance. Metal-organic frameworks (MOFs) and zeolite nanoparticles also show promise in improving salt rejection and membrane stability. The review concludes that nanomaterials offer significant advantages in RO membrane performance, but further research is needed to address challenges in scaling up and optimizing their use.This review discusses the modification of reverse osmosis (RO) membranes using nanomaterials to enhance their performance and lifespan.
