Tuning Interfacial Water Dynamics via Gd‐Doped Cu2O for High‐Rate Selective CO2‐to‐Ethanol Conversion

open access: yesAdvanced Energy Materials, EarlyView.
A Gd‐doped Cu2O electrocatalyst disrupts rigid interfacial hydrogen‐bonding networks, creating a free‐water‐rich microenvironment. This accelerates proton‐coupled electron transfer, enabling selective high‐rate CO2‐to‐ethanol conversion with 48.5% Faradaic efficiency at industrially relevant current densities.

Pyridine‐Isomerism‐Driven Spin Engineering at a COP‐Fe3O4 Interface for High‐Performance Oxygen Reduction Electrocatalysis

open access: yesAdvanced Energy Materials, EarlyView.
Strategically adjusting the pyridine nitrogen position in the polymer matrix (pyridine isomerism) intensifies its interaction with embedded Fe3O4 nanocrystals. This enhanced interaction induces a spin‐state transition in Fe from low‐spin to intermediate‐spin, accompanied by refined d‐orbital properties.

Complex Iridium Oxides Converge In Structure And Reactivity During Acidic Oxygen Evolution Electrocatalysis

open access: yesAdvanced Energy Materials, EarlyView.
Ir‐based double perovskites restructure during acidic oxygen evolution electrocatalysis through dissolution of non‐Ir cations and convergence toward IrOx active‐site motifs with similar structure and intrinsic activity across compositions. The identity of the dissolving cations controls dissolution and surface reconstruction kinetics, clarifying how ...
