Photothermally Boosted CO 2 Conversion by Silver Nanoparticles Anchored on a Bipyridinium Radical‐Functionalized Covalent Triazine Framework

ABSTRACT Developing sustainable and energy‐efficient catalytic systems for CO 2 conversion is pivotal for advancing carbon cycle management, yet remains highly challenging. Here, we report a novel near‐infrared (NIR) photothermal catalytic platform by depositing silver nanopartic...

Covalent organic frameworks for oxygen reduction: Coupling electron, proton, and molecular transport with kinetics

Abstract The oxygen reduction reaction (ORR) remains a central kinetic bottleneck in fuel cells. Its performance depends not only on catalyst activity, but also on electron/proton transfer, oxygen transport, and surface reaction kinetics. Because catalytic reactions and mass tran...

Hydrodynamic and mass transfer behaviors of NH 3 microbubbles in ionic liquids

Abstract Ionic liquids enable efficient ammonia‐containing gas separation, but conventional absorption towers suffer from limited interfacial area and mass transfer efficiency. Microchannels overcome this owing to their large specific surface area. This study investigated the hyd...

Two‐dimensional stratified ferrocene‐phosphate with adsorption–reduction coupling function for enhanced uranium capture

Abstract The development of uranium separation materials is essential to ensure a stable uranium supply for energy and to mitigate environmental risks. We report a two‐dimensional ferrocene‐vanadyl phosphate composite (fc‐VOP) with expanded interlayer spacing (9.8 Å) and adsorpti...

Dual Oxygen Precursors Boosting the Ionic Conductivity of Glassy Electrolytes for All‐Solid‐State Sodium Batteries

ABSTRACT Amorphous halide‐based solid electrolytes (SEs) are promising candidates for all‐solid‐state Na batteries (ASSNaBs) due to their structural flexibility and favorable mechanical properties. Among them, aluminum‐based halide electrolytes are particularly attractive owing t...

Sustainable Reversible Patterning via Humidity-Switchable Self-Assembled Multilayers Induced by Photolithography

Abstract Lithography plays a crucial role in the fabrication of intricate patterns. Materials that possess both lithographic capabilities and stimuli-responsive characteristics enable the realization of dynamic and controllable information processing. In this work, a self-assembl...

Crystallinity-Dependent Reverse Hydrogen Spillover Governs Electrochemical CO2 Reduction to Methane

Abstract The electrochemical CO2 reduction reaction (CO2RR) is a proton−electron coupled transfer process in which active hydrogen (*H) plays a pivotal role in determining the reaction pathways, particularly for methane (CH4), a representative deep hydrogenation product. However,...

Atomically dispersed Ti on MnOx-Fe2O3 tailors O 2p orbitals for CO oxidation and H2O/SO2 resistance

Transition-metal oxides offer a low-cost alternative to precious metals for environmental catalysis, yet CO oxidation under humid and sulfur-laden conditions remains challenging due to rapid poisoning. Herein, we report an atomic dispersion of Ti‑decorated MnOx-Fe2O3 catalyst tha...

Orbital Engineering via Double‐Exchange Interaction in a Bimetallic MOF for Electrocatalytic C─S Coupling of CO 2 and Sulfate

ABSTRACT Guided by molecular orbital theory, we have designed and synthesized a novel bimetallic metal‐organic framework (BTC‐Co‐O‐Cu‐BTA) for the electrocatalytic C─S coupling of CO 2 and sulfate. The integration of edge/corner‐sharing CoO 6 octahedra and CuO 5 square pyramids e...
