| Abstract |
Herein, we report a new metal–organic framework (MOF), namely, ECUT-77, which is built on rod-shaped secondary building units, showing a high Brunauer–Emmett–Teller surface area of 760.3 cm2/g, a pore volume of 0.4 cm3/g, and an aperture of about 1 nm. This MOF enables both high SO2 adsorption capacity up to 8.0 mmol/g at 0.92 bar and room temperature and a high SO2/CO2 selectivity of 44, resulting in excellent SO2 separation upon a ECUT-77 column from a SO2/CO2 mixture containing 2000 ppm of SO2.
