Enhancing CO2 sequestration efficiency: A comprehensive study of nanostructured MOF-composite membrane for sustainable climate solution

Abstract

This study provides a detailed exploration of nanostructured Metal-Organic Frameworks (MOFs)-composite membranes as a novel and efficient solution for CO₂ sequestration process. The integration of MOFs into membrane systems is shown to significantly enhance gas separation performance by improving both selectivity and permeability, thus addressing the inherent limitations of conventional CO₂ capture technologies. A range of synthesis techniques, including solvothermal synthesis, layer-by-layer assembly, and in-situ growth, are discussed, highlighting their role in optimizing the interaction between MOFs and membrane materials. In addition, the CO₂ capture and separation mechanism through the membrane are thoroughly discussed. The analysis further explores the impact of nanostructuring on the mechanical, chemical, and operational stability of the membranes, with particular attention to their potential for industrial scalability. Key challenges, such as MOF regeneration, economic feasibility, and environmental sustainability, are critically assessed. Additionally, the incorporation of advanced computational modelling and green synthesis methods is emphasized as essential in furthering the development of MOF-composite membranes. This study highlights the significant potential of these advanced materials to revolutionize CO₂ capture technologies, contributing to more sustainable and scalable approaches to climate change mitigation.
