Electro‐Organic Synthesis at a Stable Oil/Water/Solid Three‐Phase Interface Reactor

open access: yesAngewandte Chemie, EarlyView.
A porous membrane electrode (PME) reactor is developed to promote oil/water/solid three‐phase interfacial contact for electro‐organic synthesis. By promoting the formation of an oil/water interfacial region within or near an amphiphilic catalytic layer, the reactor enables efficient conversion of water‐insoluble organic reactants in aqueous ...

Insights into the Degradation Mechanism of Aqueous LiMn2O4–Cathode Interfaces by Computational Vibrational Spectroscopy

open access: yesAngewandte Chemie, EarlyView.
LiMn2O4${\rm LiMn}_2{\rm O}_4$ is of high interest for sustainable energy storage and conversion. Its mixed‐valence Mn3+${\rm Mn}^{3+}$/Mn4+${\text{Mn}}^{4+}$ structure drives site‐specific behavior at aqueous interfaces, featuring proton‐generating Mn4+${\text{Mn}}^{4+}$ centers and electron‐rich Mn3+${\rm Mn}^{3+}$ sites that render the surrounding ...

Interfacial Water‐Networks Regulate the Anodic Stability of Carbon Electrodes

open access: yesAngewandte 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 ...

One‐Pot Biphasic Photocatalytic CO2‐to‐Carbonylation Cascades

open access: yesAngewandte Chemie, EarlyView.
Bioinspired biphasic compartmentalization enables one‐pot cascades where photocatalytic CO2 reduction generates CO for carbonylative cross‐couplings to synthesize complex organic products, including a pharmaceutical. ABSTRACT Photosynthesis compartmentalizes reactions across the thylakoid membrane in vivo to upcycle CO2 into complex chemicals that are ...

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

open access: yesAngewandte 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

open access: yesAngewandte 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 ...

The Manifestation of the Electrochemical Potential Gradient in the Kinetic Landscapes of Interfacial Electrochemistry

open access: yesAngewandte Chemie International Edition, EarlyView.
The overpotential constitutes an electrochemical potential difference at the solid–liquid interface, which can manifest itself in different ways. In general, it can not only drive the reaction along the reaction coordinate, but also modulate chemical potentials in the extended environment that shape activation barriers, without necessarily being a ...

Graphite Co‐Intercalation Chemistry in Sodium‐Ion Batteries

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
Traditional intercalation chemistry in lithium‐ion batteries cannot allow sodium storage in graphite. The co‐intercalation chemistry changes the situation. It enables reversible and ultrafast sodium storage in graphite. Revisiting challenges and summarizing recent advances are of significant importance to exploit the full potential of graphite in ...
