Beyond Sabatier: Multiplicate Spillover Phenomena for Manipulating Catalytic Dynamics in Various Electrocatalysis

Advanced Science, EarlyView.
Various spillover‐mediated electrocatalytic reactions, such as hydrogen and oxygen evolution, carbon dioxide and nitrogen reduction, and methanol oxidization reactions, are systematically summarized. Abstract Spillover phenomenon, which is characterized by the dynamic migration of active species across catalyst surfaces, provides a promising avenue to ...

Polyoxometalate as Hydrogen–Electron Hub in Metal–Organic Complex for Electrocatalytic Nitrate Reduction to Ammonia

Advanced Science, EarlyView.
To tackle low electrocatalytic nitrate reduction to ammonia efficiency in neutral media, this work designs chain‐like dinuclear/trinuclear polyoxometalate‐based metal‐organic complexes. Metal clusters provide nitrate adsorption/activation sites, while polyoxometalates (POMs) drive water dissociation to generate active hydrogen (*H) that migrates to ...

Computation‐Guided Dual‐Site Electrocatalysts for Record‐Performance Nitrite‐to‐Ammonia Conversion

Advanced Science, EarlyView.
Designing Cu doped ZnO catalysts for NO2RR via first principles calculation and boosting electrocatalytic nitrite reduction through Cu‐ZnO synergistic deoxygenation, hydrogenation, and NH3 desorption. Cu doping elevates the d‐band center of Zn, strengthening *NO2 binding and deoxygenation, while ZnO sites regulate water adsorption and dissociation ...

Transmission of Radio‐Frequency Waves and Nuclear Magnetic Resonance in Lanthanum Superhydrides

Advanced Science, EarlyView.
1H NMR and radio‐frequency transmission measurements of lanthanum superhydrides at 165 GPa reveals a transition at 260–280 K by a strong suppression of the signal intensity, significant changes in NMR spectra, including a dramatic decrease of the relaxation rate 1/T1T, and pronounced shielding effect, which may have a superconducting nature.
