Herein, we report a new metal-organic framework (MOF), namely, , which is built on rod-shaped secondary building units, showing a high Brunauer-Emmett-Teller surface area of 760.3 cm/g, a pore volume of 0.4 cm/g, and an aperture of about 1 nm. This MOF enables both high SO adsorption capacity up to 8.0 mmol/g at 0.92 bar and room temperature and a high SO/CO selectivity of 44, resulting in excellent SO separation upon a column from a SO/CO mixture containing 2000 ppm of SO.
在此，我们报道了一种新型金属有机框架（MOF），即 ，它基于棒状二级构筑单元构建，具有760.3 cm²/g的高比表面积、0.4 cm³/g的孔体积和约1 nm的孔径。这种MOF在0.92 bar和室温下具有高达8.0 mmol/g的高SO₂吸附容量以及44的高SO₂/CO₂选择性，从而能够在填充柱上从含有2000 ppm SO₂的SO₂/CO₂混合物中实现优异的SO₂分离。
