Merging open metal sites and Lewis basic sites in a NbO-type metal–organic framework for improved C2H2/CH4 and CO2/CH4 separation
Keyword(s):
A new NbO-type metal–organic framework ZJNU-47a incorporating Lewis acidic copper sites and Lewis basic nitrogen donor sites exhibits better performance than the isostructural NOTT-101a in the separation of C2H2/CH4 and CO2/CH4 gas mixtures at room temperature.
