Cover Feature: Surveying the Homogeneity of a Molecular Electrocatalyst Embedded in a Metal‐Organic Framework Using Operando Characterization (ChemSusChem 24/2025)

Year: 2025

Type: article

Abstract: The Cover Feature shows the molecular catalyst Cu-tmpaCOOH (tmpa = tris(2-pyridylmethyl)amine) embedded in a NU1000 metal organic framework (MOF), which loses its homogeneity during the oxygen reduction reaction (ORR). Operando X-ray absorption spectroscopy (XAS) reveals that the MOF-embedded Cu molecular catalysts transform into Cu nanoclusters <2 nm, which are identified as the active and stable structures responsible for the sustained ORR activity.
