The separation performance of current physisorbents is commonly limited by insufficient C<sub>3</sub>H<sub>6</sub> binding affinity, resulting in poor low-pressure C<sub>3</sub>H<sub>6</sub> uptakes or inadequate C<sub>3</sub>H<sub>6</sub>/C<sub>2</sub>H<sub>4</sub> selectivities. Herein, we realize a unique single-molecule C<sub>3</sub>H<sub>6</sub> nanotrap in an ultramicroporous MOF material (Co(pyz)[Pd(CN)<sub>4</sub>], ZJU-74a-Pd), exhibiting the benchmark C<sub>3</sub>H<sub>6</sub> capture capacity at low-pressure regions. This MOF-based nanotrap features the sandwichlike strong multipoint binding sites and the perfect size match with C<sub>3</sub>H<sub>6</sub> molecules, providing an ultrastrong C<sub>3</sub>H<sub>6</sub> binding affinity with the maximal <i>Q</i> <sub>st</sub> value (55.8 kJ mol<sup>-1</sup>). This affords the nanotrap to exhibit one of the highest C<sub>3</sub>H<sub>6</sub> uptakes at low pressures (60.5 and 103.8 cm<sup>3</sup> cm<sup>-3</sup> at 0.01 and 0.1 bar) and record-high C<sub>3</sub>H<sub>6</sub>/C<sub>2</sub>H<sub>4</sub> selectivity (23.4). Theoretical calculations reveal that the perfectly size-matched pore cavities combined with sandwichlike multibinding sites enable this single-molecule C<sub>3</sub>H<sub>6</sub> nanotrap to maximize the C<sub>3</sub>H<sub>6</sub> binding affinity, mainly accounting for its record low-pressure C<sub>3</sub>H<sub>6</sub> capture capacity and selectivity. Breakthrough experiments further confirm its excellent separation capacity for actual 1/99 and 50/50 C<sub>3</sub>H<sub>6</sub>/C<sub>2</sub>H<sub>4</sub> mixtures, affording the remarkably high pure C<sub>2</sub>H<sub>4</sub> productivities of 17.1 and 3.4 mol kg<sup>-1</sup>, respectively.</p>","PeriodicalId":100230,"journal":{"name":"Chem & Bio Engineering","volume":"1 11","pages":"952-959"},"PeriodicalIF":0.0,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11835284/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143461489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
