Bioinspired Water-Stable Sc-MOF with Amino-Barb Vigreux-Type Channels for One-Step Ethylene Purification
We report a bioinspired Sc-MOF <b>NTUniv-77</b> with Vigreux-type channels and amino-barb protrusions that enable selective gas adsorption. The unique amino group arrangement facilitates multistage cascade separation, enhancing C<sub>2</sub>H<sub>2</sub> and C<sub>2</sub>H<sub>6</sub> adsorption while allowing high-purity C<sub>2</sub>H<sub>4</sub> purification in a single step. <b>NTUniv-77</b> shows outstanding separation performance, with a C<sub>2</sub>H<sub>2</sub>/C<sub>2</sub>H<sub>4</sub> (1:99) selectivity of 42 and C<sub>2</sub>H<sub>6</sub>/C<sub>2</sub>H<sub>4</sub> (1:9) selectivity of 3.6, surpassing benchmark MOFs. GCMC simulations reveal that hydrogen bonding interactions at amino-barb sites are key to its efficiency. Breakthrough experiments confirmed the efficient separation of C2 gases, yielding high-purity C<sub>2</sub>H<sub>4</sub> with a production capacity of 1.29 mmol g<sup>-1</sup>.
