A series of isostructural polyoxometalate-based metal–organic frameworks of 3,5-bis(1′,2′,4′-triazol-1′-yl)pyridine: synthesis, structures and electrocatalytic properties

Abstract

Three isostructural polyoxometalate-based metal–organic frameworks (POMOFs) [M^II₂(btap)₂(β-Mo₈O₂₆)(H₂O)₄]·4H₂O (M = Co 1, Ni 2, Zn 3) based on octamolybdate and 3,5-bis(1′,2′,4′-triazol-1′-yl)pyridine (btap) were synthesized via the hydrothermal method. POMOFs 1 and 2 and their thermal derivatives could be utilized as efficient electrocatalysts for the oxygen evolution reaction.
