Combining unsaturated metal sites and narrow pores within a Co(ii)-based MOF towards CO2 separation and transformation

摘要

A Co(ii)-based MOF, {[Co-3(L)(2)(bpb)(DMA)(H2O)]Solvents}(n) (RH-1), with a unique interpenetrated framework has been solvothermally prepared. Because of its unsaturated metal sites and narrow pores inside the framework, RH-1 demonstrated excellent selective CO2 adsorption over N-2 and CH4 and good performance in catalytic CO2 conversion to cyclic carbonates under mild conditions.
