A 3D non-interpenetrating porous metal-organic framework [Pb2(H2TCPP)]·4DMF·H2O (Pb-TCPP) (H6TCPP = 5,10,15,20-tetra(carboxyphenyl)porphyrin) was synthesized by employment of a robust porphyrin ligand. Pb-TCPP exhibits a one-dimensional channel possessing fairly good capability of gas sorption for N2, H2, Ar, and CO2 gases, and also features selectivity for CO2 over CH4 at 298 K. Furthermore, Pb-TCPP shows electrocatalytic activity for water oxidation in alkaline solution. It is the first 3D porous Pb-MOF that exhibits both gas adsorption properties and electrocatalytic activity for an oxygen evolution reaction (OER).
通过使用一种稳定的卟啉配体合成了一种三维非互穿多孔金属有机框架[Pb2(H2TCPP)]·4DMF·H2O（Pb-TCPP）（H6TCPP = 5,10,15,20-四（羧基苯基）卟啉）。Pb-TCPP具有一维通道，对N2、H2、Ar和CO2气体具有相当好的气体吸附能力，并且在298 K时对CO2具有优于CH4的选择性。此外，Pb-TCPP在碱性溶液中对水氧化表现出电催化活性。它是第一个既表现出气体吸附性能又对析氧反应（OER）具有电催化活性的三维多孔铅基金属有机框架。
