Synergistic Effect of Active Sites and a Multiple-Micropore System for a Metal–Organic Framework Exhibiting High Separation of CO₂/CH₄ and C₂H₂/CH₄

Efficient gas separation and purification play a vital role in the current advanced development of industry, and the application of MOF adsorbents in this area with highly technical materials shows obvious advantages. On the basis of reticular chemistry, the 4-c lvt MOF adsorbent [CuDTTA]·3DMF·CH3CN has been constructed (CuDTTA; H2DTTA = 2,5-bis(1H-1,2,4-triazol-1-yl)terephthalic acid). CuDTTA reveals a multiple-micropore system and high-density...
