Abstract

Graphical abstract: A microporous metal–organic framework with optimized pore space and functional sites was synthesized to realize high acetylene storage and selectivity separation for C2 H2 /CH4 and CO2 /CH4 . Abstract: A microporous metal–organic framework (MOF), Cu6 (ABTC)3 (H2 O)6 ·(DMA)7 (H2 O)12 (Cu-ABTC, H4 ABTC = 3, 3′, 5, 5′-azobenzenetetracarboxylic acid) was solvothermal obtained and structurally characterized. The activatedCu-ABTC-a exhibits high BET specific surface area of 2366 m 2 /g. Due to optimized pore space and open Cu 2+ functional sites, Cu-ABTC-a displays high C2 H2 storage capacity of 208 cm 3 g −1 at 298 K and separation selectivities for equimolar C2 H2 /CH4 and CO2 /CH4 at 298 K, respectively.
