High‐Concentration Alcohol Generation in Bipolar Membrane CO Electrolyzer

open access: yesAngewandte Chemie, EarlyView.
This study presents a forward‐biased bipolar membrane (FB‐BPM) CO electrolyzer that reduces liquid product crossover to <10% (8x lower than conventional designs) while minimizing hydrogen production and in favor of multicarbon liquid species. By engineering catalyst morphology to modulate the binding of *CO, *H, and *OH intermediates, we identified a ...

Switchable Reactivities of Metalated Phosphasilenes Regulated by Reversible 1,2‐Metal Migration

open access: yesAngewandte Chemie, EarlyView.
We develop novel strategies for the facile synthesis of anionic phosphasilenes in the forms of both P‐metalation and Si‐metalation. The P‐metalated phosphasilene displays a pronounced π‐bond‐driven reactivity toward robust inert molecules, whereas the Si‐metalated analogue behaves as a silylene equivalent via a retro‐1,2‐silver migration.

Local Coordination‐Dependent CO2 Reduction Activity of Bimetallic Cu─Al Catalysts for Selective Ethylene/Ethanol Electrosynthesis

open access: yesAngewandte Chemie, EarlyView.
While bimetallic catalysts enhance C2+ yield, product selectivity remains elusive. We demonstrate that atomic coordination governs the bifurcation at the *CHCOH intermediate: Cu/CuAlO2 interface‐rich catalyst cleaves C–O to favor ethylene, whereas Al‐doped Cu catalyst breaks Cu–C to boost ethanol.

Selective, Oxygen‐Tunable, and Metal‐Free Functionalization of Polyethylene Through Dual‐Mode Nitrosation and Carbonylation

open access: yesAngewandte Chemie, EarlyView.
A metal‐free nitrosation process enables direct C–H functionalization of polyethylene (PE) with high selectivity, producing either oxime‐ or carbonyl‐functionalized polymers. Using t‐BuONO under visible light or thermal conditions, the process operates in both lab‐scale and industrial settings.
