Microporous Metal-Organic Framework with Potential for Carbon Dioxide Capture at Ambient Conditions



Shengchang Xiang, Yabing He, Zhangjing Zhang, Hui Wu, Wei Zhou, Rajamani Krishna, Banglin Chen


Carbon dioxide capture and sequestration (CCS) is a very important industrial and environmental process to make use of the carbon dioxide as raw chemical for the production of a range of chemical products and materials, and to minimize the effect of carbon dioxide emission on the potential global warming. Current technology using aqueous absorbents to chemically absorb carbon dioxide is very energy consuming and environmentally unfriendly. Porous metal-organic frameworks (MOFs) are promising for CCS; however, very rare MOF materials exhibiting extremely high capacities and selectivities at ambient conditions (room temperature and 1 bar) for CCS have been realized. Here, we report a very unique microporous MOF (UTSA-16) displaying extraordinarily high uptake of carbon dioxide (160 cm3/cm3 at 1 bar and 296 K work), enabling it to be very practically useful MOF material for the post-combustion carbon dioxide capture and nature gas sweetening which have been further confirmed by simulated breakthrough experiments. The high storage capacities and selectivities of UTSA-16 for CCS are attributed to the optimal pore cages and the strong binding sites for the capture of carbon dioxide which have been exclusively established by neutron diffraction studies.
