A 3D non-interpenetrating porous metal–organic framework shows electrocatalytic activity for water oxidation in alkaline solution.
A 3D non-interpenetrating porous metal–organic framework [Pb 2(H 2TCPP)]·4DMF·H 2O (Pb-TCPP) (H 6TCPP = 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 N 2, H 2, Ar, and CO 2 gases, and also features selectivity for CO 2 over CH 4 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).
