Metal-organic frameworks (MOFs) represent a versatile class of nanoporous materials with immense potential in gas separation, chemical sensing, and catalysis. However, conventional synthesis methods (e.g., hydrothermal and solvothermal) often face challenges related to scalability, environmental impact, and integration into practical devices. This talk presents a comprehensive overview of recent advancements in green and scalable manufacturing strategies for MOF-based composites, highlighting innovative solution-phase, vapor-phase, and electrochemical approaches that enable rapid, low-temperature, and solvent-free processing. Emphasis will be placed on the integration of MOFs onto diverse substrates, including polymeric textiles, inorganic porous membranes, and thin films, to create multifunctional composites tailored for energy and environmental applications. By bridging materials chemistry with sustainable processing, this talk outlines a pathway toward next-generation MOF-based technologies with reduced ecological footprints and enhanced performance for real-world deployment.
