Metal Active‐Site Exposure via Ligand Engineering Boosts CO2‐to‐Ethylene Conversion on Cu18 Nanoclusters

Advanced Science, EarlyView.
Through quantitative ligand stripping of [Cu18H17(PR3)10]+ nanoclusters via intramolecular interaction modulation, selectivity for CO2 electroreduction to C2H4 is significantly enhanced. The weakly coordinating ligand triggers dual‐ligand stripping (FEC2H4 = 70.59%), whereas the strongly coordinating ligand results in single‐ligand retention (FEC2H4 ...

Nanocluster‐Assisted OH Ligand Modification Optimizes Activity and Stability of Fe‐N‐C Catalysts

Advanced Science, EarlyView.
A nanocluster‐assisted ligand engineering stabilizes OH‐modified FeN4 active sites through strong electronic coupling between isolated Fe atoms and adjacent nanoclusters. This synergy optimizes oxygen‐intermediate adsorption, lowers ORR energy barriers, and breaks the conventional activity–stability trade‐off, enabling high ORR activity, exceptional ...
