*OH Adsorption‐Mediated Electrochemical Oxidation of 5‐Hydroxymethylfurfural to Selective 2,5‐Furandicarboxylic Acid at pH 12

open access: yesAdvanced Science, EarlyView.
Under the weakly alkaline condition, at pH 12, the *OH adsorption–mediated mechanism of direct aldehyde oxidation is demonstrated to complete HMF oxidation to FDCA, obtaining >95% selectivity and yield. In OH−‐deficient media, high FDCA selectivity is achieved on the CuO/NiOOH interface, a synergistic active site, where Cu enhances *OH utilization, and

Unraveling the Origin of Exceptional Activity in NiMo Alloys for Alkaline Hydrogen Evolution

open access: yesAdvanced Science, EarlyView.
This study resolves the controversy regarding the active origin of Nickel‐molybdenum (NiMo) alloys for alkaline hydrogen evolution. By combining surface Pourbaix diagrams with microkinetic modeling, we demonstrate that the O‐covered Ni3Mo surface drives activity through a synergistic mechanism: Mo sites facilitate water dissociation while adjacent Ni ...

Enhanced Oxygen Redox Activity and Structure Stability of P2‐Type Manganese‐Based Cathodes Through Medium‐Entropy Strategy

open access: yesAdvanced Science, EarlyView.
A medium‐entropy strategy guided by ionic potential is applied to weaken TM─O bonds and suppress Jahn–Teller distortion in P2‐type cathodes, thereby enhancing the oxygen redox activity and structure stability. A medium‐entropy oxide, Na0.8Li0.1Ni0.1Cu0.1Ti0.1Mn0.6O2, demonstrates a high reversible capacity of 223.7 mAh g−1 and an energy density of 616 ...

Room‐Temperature Alane Dehydrogenation for Visible‐Light‐Driven Photocatalytic Hydrogen Supply System

open access: yesAdvanced Science, EarlyView.
In situ formed Al/MOF enables viable visible‐light‐driven photocatalytic dehydrogenation of alane (AlH3) confirming practical application. Results demonstrate that Al nanoparticles prolong lifetime of photogenerated charge carriers via localized surface plasmon resonance induced hot electron injection, while AlH3 chemisorption triggers interfacial ...

Hierarchical Embedded Sphere Model: An Interpretable ML‐Guided Multiscale Descriptor Engineering Decodes OER Activity on TM@MO2 Catalysts

open access: yesAdvanced Science, EarlyView.
Hierarchical Embedded Sphere Model combines DFT and interpretable machine learning to decode catalytic activity on TM‐doped MO2. It disentangles global electronic, active‐site, and local coordination effects, revealing two activation mechanisms: dopant‐driven (Rh@MO2) and coordination‐mediated (Fe@ZrO2).

Reaction Mechanism, Challenges, and Strategies of High‐Energy‐Density Sodium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
Focusing on high‐energy‐density sodium‐ion batteries, this review highlights the advantages offered by conversion‐type cathode materials. The currently studied cathode materials are systematically introduced. By analyzing sulfur, oxygen, and transition metal halides and other conversion‐type cathodes, the key challenges associated with these cathodes ...
