Directional Second Sphere Effect on CO2 Activation and Reduction by Iron Porphyrin in Aprotic and Protic Media

Angewandte Chemie, EarlyView.
Directional control within the secondary coordination sphere redefines CO2 reduction by iron porphyrins. Simply rearranging identical urea hydrogen‐bond donors modulates reactivity, revealing that optimal catalysis does not only arise from maximal intermediate stabilization, but also from directional, adaptive non‐covalent interactions that balance ...

Multiscale Design of Anion Exchange Membrane‐Based Seawater Electrolysis for Sustainable Hydrogen Production

Advanced Energy Materials, EarlyView.
Direct seawater electrolysis using anion exchange membranes is emerging as a promising route for sustainable hydrogen production. This review summarizes multiscale design strategies from seawater chemistry and OER–ClER selectivity to catalysts, membranes, MEAs, cells, stacks, and system integration, providing a roadmap toward selective, durable, and ...

Enriched and Sustained Oxygen Vacancies in Amorphous NiWOx Enhance and Stabilize Urea Electrooxidation

Angewandte Chemie, EarlyView.
We propose an “amorphous oxygen mechanism (AOM)” for urea electrooxidation on amorphous NiWOx with tunable Ov, which achieves robust UOR activity and stability simultaneously. The “amorphous oxygen” in NiWOx prefers to escape during the UOR, in situ generating and stabilizing Ov, which thermodynamically promotes the reaction.

FastCat: Autonomous Discovery of Multielement Layered Double Hydroxide Alloy Catalysts for Alkaline Oxygen Evolution Reaction

Advanced Intelligent Discovery, EarlyView.
A machine learning‐guided self‐driving laboratory screened over 500 nickel‐based layered double‐hydroxide catalysts for alkaline oxygen evolution. Out of the eight metals, the robot uncovered a quaternary Ni–Fe–Cr–Co catalysts requiring only 231 mV overpotential to reach 20 mA cm−2.

Microenvironment Engineering as a Design Principle for Suppressing Catalyst Metal Loss

Angewandte Chemie, EarlyView.
Under ionomer‐containing microenvironments, nonporous carbon supports enhance the retention of dissolved platinum ions, whereas porous carbon supports promote pore‐confined redeposition and mitigate net platinum loss. ABSTRACT Stability losses in platinum electrocatalysts arise from dissolution, redeposition, and restructuring processes that are ...

Charge‐Transfer Assembly of Electrically Conductive Metal–Organic Cages

Angewandte Chemie, EarlyView.
Electrically conductive and permanently porous metal–organic cages are realized using charge‐transfer assembly between electron‐donating cages and electron‐accepting molecules, which self‐assemble to create new charge transport pathways without sacrificing access to internal void space.
