A new microporous metal–organic framework with open metal sites and exposed carboxylic acid groups for selective separation of CO2/CH4 and C2H2/CH4

A new microporous metal–organic framework Cu6(DDCBA)3 (ZJU-72, H5DDCBA = 3,5-di(3′,5′-dicarboxylpheny)-benozoic acid) with open metal sites and exposed carboxylate groups is rationally designed and synthesized, exhibiting a low binding energy of 9.7 kJ mol−1 for C2H2 and 15.1 kJ mol−1 for CO2 and a high separation selectivity of 39.7 for C2H2/CH4 at 298 K and 8.2 for CO2/CH4 at 273 K.

An amino-decorated NbO-type metal–organic framework for high C2H2 storage and selective CO2 capture

A novel amino-decorated NbO-type metal–organic framework [Cu2(C22H11NO8)(H2O)2]·(DMF)6·(H2O), (ZJU-8, ZJU = Zhejiang University; DMF = N,N-dimethylformamide) has been synthesized and structurally characterized. The activated ZJU-8a exhibits both a high C2H2 uptake capacity (195 cm3 g−1 at 1 bar) and a moderately high adsorption selectivity for CO2 over N2 (12.27) and CH4 (7.38) at room temperature.

A new NbO type metal–organic framework for high acetylene and methane storage

A new NbO type metal–organic framework [Cu2(NPA)(H2O)2](DMF)5.5(H2O)0.5 (ZJU-9, H4NPA = 1,5-naphthalene-m-phthalic acid) with moderately high permanent porosity, open metal sites and appropriate pore sizes was designed and synthesized, exhibiting high storage capacities for both acetylene and methane at room temperature.
