摘要

A methoxy-decorated novel metal-organic framework (MOF), Cu-2(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 m(2) 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 cm(3) g(-1) and CO2 capture capacity of 134 cm(3) g(-1) at room temperature.
