Coordinating Mesopore Geometry and Interfacial Water Dynamics for Iron‐Site Evolution in Nitrate Electroreduction

Angewandte Chemie, EarlyView.
Mesopore geometry programs the working‐state interface of Fe single sites during nitrate electroreduction. Hexagonal channels reorganize interfacial water and accompany the reversible evolution of isolated Fe─O4‐like sites toward Fe─O─Fe‐like motifs, promoting successive hydrogenation toward NH3 with a Faradaic efficiency of 99.1%.

Interfacial Water‐Networks Regulate the Anodic Stability of Carbon Electrodes

Angewandte Chemie, EarlyView.
The hydrogen‐bonding networks of interfacial water serve as active stability descriptors for carbon anodes: disrupted water‐networks accelerate anodic carbon corrosion, whereas strongly hydrogen‐bonded networks suppress it. This principle enables extension of the stable potential window of carbon electrodes through ionomer‐defined interfaces, as ...

Direct Observation of Radical‐Mediated Oxide‐to‐Alloy Transformation in Solution Under Pulsed Laser Irradiation

Angewandte Chemie, EarlyView.
Time‐resolved in situ x‐ray absorption spectroscopy and DFTB‐based molecular dynamics simulations identify direct hydrogen atom transfer from ethanol to lattice oxygen as the elementary step of laser‐driven reduction in NiCo2O4. While this transfer is facile, the subsequent release of lattice oxygen is entropy‐driven and becomes accessible only at ...

Rerouting Oxygen Evolution Through Interfacial Carbonate Chemistry in Near‐Neutral Seawater Electrolysis

Angewandte Chemie, EarlyView.
Carbonate species play a previously overlooked role in near‐neutral seawater electrocatalysis. By coupling electrochemical hydrodynamics with mesoscopic simulations, we reveal a plausible carbonate‐mediated route in which carbonate functions as an interfacial proton acceptor and water as the oxygen donor, showing a possible mechanistic picture of ...
