Electrified Acetylene Removal From Ethylene Streams Enabled by Facet‐Engineered Cu–TiO2 Interfaces

Angewandte Chemie, EarlyView.
Facet‐engineered interfaces enable selective electrochemical acetylene removal from ethylene streams. Dispersed Cu nanoclusters on the titania {001} facet suppress hydrogen and coupling byproducts, while stabilizing key hydrogenation intermediates.

Water‐Mediated Proton Facilitation for Stable Acidic CO2 Electrocatalysis

Advanced Energy Materials, EarlyView.
Proton‐mitigating Cu─O─Ce sites accelerate *CO formation and PCET‐mediated *CO─*CHO coupling, enabling efficient multicarbon production at relatively low current density. Maintaining a retentive acidic pH suppresses parasitic hydrogen evolution and preserves in situ CO2 availability for carbon‐efficient acidic CO2 reduction.

Programming Structural Disorder in MOFs for a Stable Bifunctional Water‐Splitting Electrocatalyst

Advanced Energy Materials, EarlyView.
Introducing structural disorder into a highly active metal–organic framework enhances its stability. This improvement arises from the mitigation of destructive reconstruction during activation, thereby maintaining structural integrity and enabling long‐term durability.

Spin‐Polarized Interfaces Redirect CO2 Reduction From CO to Formate

Angewandte Chemie, EarlyView.
The chiral electrocatalyst exploits the CISS effect to establish a spin‐polarized interface that selectively promotes formate production during CO2 reduction while effectively suppressing the competing hydrogen evolution. ABSTRACT Achieving high product selectivity in electrocatalytic carbon dioxide reduction (CO2RR) remains a critical challenge due to

Electron Bridge Enhanced Charge Polarization Enables Efficient and Ultra‐Long Stable Urea Electrosynthesis

Angewandte Chemie, EarlyView.
An electron bridge strategy is developed to regulate charge polarization in Pd1 and Ni1 dual single‐atom sites, promoting CO2 reduction, nitrate reduction, and C–N coupling simultaneously. The resulting catalyst achieves efficient urea electrosynthesis with high activity and record durability over 1700 h.

Alkoxyethyl Acetate Electrolytes for High‐Voltage Lithium Metal Batteries

Angewandte Chemie, EarlyView.
We designed a fluorinated alkoxyethyl acetate solvent for high‐voltage Li‖NMC811 batteries. Introducing a carbonyl group disrupts symmetric bidentate solvation, while terminal fluorination enhances high‐voltage stability and reversible Li plating/stripping. The tailored solvation promotes a robust cathode electrolyte interphase, substantially extending
