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

open access: yesAdvanced 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

open access: yesAdvanced 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 ...

Large igneous provinces played a major role in oceanic oxygenation events during the mid-Proterozoic

open access: yesCommunications Earth & Environment
Low atmospheric oxygen levels during the mid-Proterozoic were occasionally interrupted by transient high oxygen levels. The cause of mid-Proterozoic ocean redox variability remains unclear.

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

open access: yesAdvanced 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 ...
