Engineering Active Metal and Nonmetal Sites in Porous Structures of Metal‐Hydroxide Clusters for Enhanced D2/H2 Uptake and Separation

open access: yesAdvanced Science, EarlyView.
Two supramolecular assembly frameworks, constructed from metal‐hydroxide clusters, are synthesized via coordination‐driven self‐assembly mediated by Co2+ and Cu2+ metal centers. One of them demonstrates exceptional D2 and H2 uptake capabilities, achieving the second‐highest uptake capacity for D2.

Methylation‐Induced Permanent Charge Polarization in Covalent Organic Frameworks for Visible Light‐Driven Water Decontamination and Disinfection

open access: yesAdvanced Science, EarlyView.
A targeted in situ methylation strategy is developed to engineer cationic centers in a quinoline‐linked COF (NQ‐COFS1‐Me), creating a strong built‐in electric field, which effectively suppresses excitonic effects and promotes charge separation. The optimized material demonstrates powerful photocatalytic ROS generation for rapid bacterial inactivation ...

Asymmetric Cu─N─Ru Bridgedsite Nanozyme‐Loaded Injectable Thermogel Boosts Cuproptosis‐Like Death for Multidrug‐Resistant Urinary Tract Infections

open access: yesAdvanced Science, EarlyView.
To address multidrug‐resistant urinary tract infections (MDR‐UTIs), we developed Cu‐ZIF8‐Ru nanozyme featuring an asymmetric Cu─N─Ru catalytic site. This unique structure enhances multienzyme‐mimetic activity, eradicating resistant bacteria by inducing a cuproptosis‐like death pathway through intracellular Cu2+ accumulation and energy depletion.

Selective Confinement by a COF‐Derived Sub‐Nanoporous Interface for High‐Performance CoF2 Thermal Battery Cathodes

open access: yesAdvanced Science, EarlyView.
Dissolution and shuttling of TMF cathodes hinders high‐voltage thermal batteries. A novel selective confinement strategy using a sub‐nanoporous COF‐derived carbon interface (0.54 nm pores) on CoF2 suppresses cathode material shuttling. Size‐selective confinement blocks large dissolved ions (∼0.8 nm) while allowing Li⁺ passage, enhancing thermal battery

Photocatalytic Asymmetric C‐C Coupling for CO2 Reduction on Cu‐Zn Bimetallic Catalysts with Dipole‐Limiting Effects

open access: yesAdvanced Science, EarlyView.
Asymmetric Cu–Zn dual sites on EDTA‐grafted Ti‐MOF amplify the dipole‐limiting domain field (DLDF), facilitating C–C coupling. This strategy yields an exceptional C2H4 production rate of 308.72 µmol g−1 h−1 with 98.4% electron selectivity in photocatalytic CO2 reduction, highlighting the potential of asymmetric site engineering and local field ...
