Abstract
En 中文
Forward Osmosis (FO) has been increasingly used in water treatment due to its energy efficiency and ability to address water scarcity issues effectively. However, FO thin-film composite (TFC) membranes face challenges such as low water flux, internal concentration polarization, and reverse salt flux, which limit their performance. The incorporation of metal-organic frameworks (MOFs) into TFC membranes has shown significant potential in overcoming these limitations by improving selective transport, enhancing antifouling properties, and increasing membrane efficiency. This review examines various strategies for MOF integration, including incorporation in the polyamide layer, deposition in the interlayer, and embedding in the substrate layer. The effects of these integration approaches on membrane structure, performance, and stability are discussed. Additionally, challenges such as MOF stability in aqueous environments, agglomeration, and long-term durability are addressed. Emerging techniques, such as artificial intelligence-driven MOF selection and optimization, are also explored as promising solutions to accelerate research and development. The review concludes by proposing future research directions to overcome existing barriers, focusing on optimizing MOF properties, enhancing membrane stability, and achieving sustainable water treatment solutions.
