摘要: Abstract Three metal–organic frameworks Zn5(μ-OH)(BTC)3(phen)4·5H2O (HUT-11), Ce5(μ-OH)(BTC)3 (phen)4 (HUT-091) and Mn5(μ-OH)(BTC)3(phen)4·5H2O (HUT-101) have been synthesized, based on the ligands of 1,3,5-benzenetricarboxylic acid (H3BTC) phenanthroline (phen) in presence Zn, Ce Mn metal ions. The flexible ligand BTC gives remarkable properties microporous coordination polymers, that exhibits infrequent (3,4,5)-connected (4·6·8)2(4·82)(42·62·82)(42·82·102)(4·64·85) topology by using or clusters H3BTC as nodes. thermal stability each compounds relies atmosphere Ce-MOFs stabilize till 600 °C N2. photocatalytic Zn-MOFs reduction Cr6+ also studied are more active can be recycled at least three times.
