Rapidly increasing atmospheric CO2 concentrations threaten human society, the natural environment, and synergy between two. In order to ameliorate problem, carbon capture conversion techniques have been proposed. Metal-organic framework (MOF)-based materials, a relatively new class of porous materials with unique structural features, high surface areas, chemical tunability stability, extensively studied respect their applicability such techniques. Recently, it has become apparent that capabilities MOF-based significantly boost potential toward conversion. Furthermore, materials' well-defined structures greatly facilitate understanding structure-property relationships roles in this review, we provide comprehensive account significant progress design synthesis including MOFs, MOF composites derivatives, application Special emphases on capacities catalytic performances are discussed.
