Unraveling Alkali Ion Electron Donation for Enhancing Heterogeneous Catalytic Oxidation

open access: yesAdvanced Science, EarlyView.
A new mechanistic pathway for potassium (K) ions as electron donors is identified by constructing single K ion chains confined within hexagonal WO3 tunnels. The as‐produced high‐electron‐density Kδ+ (0<δ<1) ions not only facilitate the formation of oxygen vacancies that behave classical electronic effect but, more importantly, also directly donate ...

Iron Nanoparticles on Porous Carbon Discs: Electrocatalysts with Over 30% Energy Efficiencies for the Production of Ammonia from Nitrate

open access: yesAdvanced Science, EarlyView.
Iron nanoparticles on carbon disc matrixes (CD@Fe) are engineered, showing a high surface area of 424 m2 g−1 and micro/mesoporosity. The CD@Fe showed promising electrocatalytic performance for the nitrate reduction to ammonia with ammonia yield rates of 1.8–13.5 mg h−1 cm−2 at overpotentials of −0.2–−0.6 V (vs.

Knowledge Graph for Methane Selective Conversion: Revisiting and Predicting Product Selectivity and Methane Conversion

open access: yesAdvanced Science, EarlyView.
With the help of large language models, deep neural network learning, and kinetic calculation, a knowledge graph prediction of prior research in methane conversion is conducted. This knowledge graph provides a comprehensive understanding of the relationships among catalyst materials, catalytic performance, and reaction conditions, providing guidance ...
