A novel methoxy-decorated metal–organic framework exhibiting high acetylene and carbon dioxide storage capacities

A methoxy-decorated novel metal–organic framework (MOF), Cu2(DTPD) (ZJU-12, H4DTPD = 5,5′-(2,6-dimethoxynaphthalene-1,5-diyl)diisophthalic acid) with optimized pore space and open metal sites, was solvothermally synthesized and structurally characterized. The activated ZJU-12a displays a moderately high BET (Brunauer–Emmett–Teller) surface area of 2316 m2 g−1. Due to the pore size of the crystal being consistent with the molecular size and kinetic diameters of C2H2 and CO2, ZJU-12a exhibits a high C2H2 storage capacity of 244 cm3 g−1 and CO2 capture capacity of 134 cm3 g−1 at room temperature.
