Highly selective C2H2 and CO2 capture based on two new ZnII-MOFs and fluorescence sensing of two doped MOFs with EuIII

Two Zn( ii )-based MOFs have been constructed. The activated Zn-MOF 1 and Zn-MOF 2 show selective separation of C 2 H 2 and CO 2 over CH 4 . Eu@Zn-MOF 1 and Eu@Zn-MOF 2 were obtained by adding Eu III ions and showed selectivity to Fe 3+ ions in aqueous solution.
