Single-Cluster Polyoxometalate Catalysts via Modular Electrostatic Assembly on Cationic Covalent Organic Framework for Furfural Electroreduction

Single-cluster catalysts (SCCs) provide atomically precise active sites and model systems for mechanistic studies, but achieving uniform dispersion of clusters on supports remains challenging. Herein, a cationic porphyrin–viologen covalent organic...
