Lowering CO 2 emissions and the concentration of greenhouse gasses become major concern to overcome the global warming issue. One method to reduce CO 2 emissions is to implement the carbon capture and storage (CCS). In addition to developing the CCS technology, the investigations on materials that have high gas separation performance and low costs are also widely executed. A new type of crystalline porous material, metal-organic framework (MOF), which consists of metal ions and organic ligands in recent years as a promising type of adsorbent has emerged. MIL-101 Cr which is comprised of trimeric chromium (III) octahedral connected to 1,4- benzenedicarboxylates, one type of MOF, has attracted a lot of attention among researchers to develop the performance of CO 2 adsorption, since this chromium terephthalate has a large pore size (29 and 34 Å) and specific surface area attaining to more than 3,000 m 2 /g. Thermal stability and moisture resistance of this adsorbent make this material easily modified in post-synthesis, organic functionalization, cation doping, and composite type of MOF. In this study, we review the research and development of the synthesis, functionalization, and modification for the application of CO 2 adsorption in MIL-101 Cr.
