Application of MOF-808 and its derivatives in carbon capture and CO2 catalytic conversion

Abstract

Excessive emissions of CO₂, the main component of greenhouse gases, have led to frequent natural disasters worldwide and a global movement towards carbon neutrality. Carbon Capture, utilisation and storage (CCUS) has attracted research interest as a sustainable emission reduction technology. Metal–organic frameworks (MOFs) stand out as a new class of high-performance adsorbents with significant advantages for CO₂ capture. Their extraordinarily high specific surface area and well-developed pore structure make them ideal for this application. In recent years, significant progress has been made in the research of MOF-808 and its derivatives for CO₂ capture, separation, and catalytic utilization. Several important findings have been published, substantially advancing the practical applications of MOF-808 materials in carbon capture technology. However, a comprehensive summary of these developments is still lacking. Therefore, this paper reviews recent research progress on MOF-808 and its derivatives for CO₂ applications. It provides an in-depth analysis of advanced synthesis methods and optimization strategies for MOF-808 and its derived materials in CO₂ selective adsorption, separation and catalysis while exploring the mechanisms underlying CO₂ capture, separation and catalytic processes. Moreover, this paper systematically summarises the key issues that have attracted much attention regarding MOF-808 materials in carbon capture and practical applications. Finally, the challenges and opportunities of MOF-808 materials in the context of CO₂ adsorption, separation and catalytic utilization are described.
