FeCoNiCuPt High‐Entropy Alloy Boosts Photocatalytic Hydrogen Production on Protonated Graphitic Carbon Nitride

open access: yesAdvanced Science, EarlyView.
In this study, FeCoNiCuPt high‐entropy alloy particles (HEA) are loaded onto protonated g‐C3N4 nanosheets (HCN NSs) to construct HEA/HCN composites through an electrostatic self‐assembly method. Protonation treatment enriches the surface of g‐C3N4 nanosheets with abundant active sites and enhances their interfacial charge separation capability ...

In Situ Elucidations of the Mechanism for Inert Molecular N2O Decomposition at Low Temperature Catalyzed by High‐Index Interfacial Exposed Co3O4

open access: yesAdvanced Science, EarlyView.
This study develops a co‐precipitation followed by hydrothermal synthesis strategy for synthesizing Co3O4 catalyst with multiple high‐index facets. Experiments and density functional theory calculations demonstrate that Co3+ on the (400–400) facet can form a novel active Co3+‐O* motif during the reaction.

Electride‐Induced Electronic Modulation of Ruthenium Catalyst for Highly Efficient Alkaline Hydrogen Evolution

open access: yesAdvanced Science, EarlyView.
Electrides offer unique opportunities as catalyst supports for hydrogen evolution reactions. This study presents an electride‐supported Ru/Nd2ScSi2 catalyst exhibiting outstanding hydrogen evolution reaction performance and excellent stability. Anionic Ru species on the electride surface facilitate water dissociation and optimize hydrogen adsorption ...

Improved Molybdenum Dioxide Atomic Layer Deposition Process by Introducing Pre‐Reduction Agent

open access: yesAdvanced Electronic Materials, EarlyView.
This study investigates MoO2 thin films deposited by ALD as electrode materials for next‐generation DRAM capacitors. A pre‐reduction step using ethanol is introduced to control the oxidation state of MoOx and to suppress surface morphology degradation.
