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