Laterally Oriented Dendritic Passivation via In Situ Zn Reconstruction for Stabilizing NiMo Catalysts under Dynamic Electrolysis

open access: yesAdvanced Science, EarlyView.
This study highlights the effectiveness of Zn‐induced dendrite layers in enhancing the durability of NiMo HER catalysts under dynamic electrochemical conditions. Through in situ dendritic passivation, the Zn‐NiMo catalyst preserves catalytic active sites and mitigates irreversible Ni oxidation/hydroxylation during repeated load fluctuation.

Passivation‐Induced Species Dynamics and Microstructural Evolution in Solid‐State Lithium–Sulfur Cathodes

open access: yesAdvanced Science, EarlyView.
The formation of insulating Li2S during discharge in solid‐state lithium–sulfur batteries passivate reaction sites and limits sulfur utilization. In this work, a microstructure‐resolved modeling framework coupling transport and reaction kinetics is developed to predict charge–discharge behavior and reveal particle‐scale species evolution and incomplete

Interfacially Coupled and Synergistic Effect of Ag/Co3O4‐C Nanocomposites for Enhanced Oxygen Reduction (ORR) and Evolution (OER) Reaction

open access: yesAdvanced Science, EarlyView.
Ag/Co3O4–C nanocomposites display well‐resolved lattice fringes and synergistic Ag/Co3O4 heterointerfaces that enhance charge transfer and active‐site exposure. The structural design enables superior bifunctional ORR/OER performance in alkaline media by promoting efficient adsorption and turnover of oxygen intermediates within an optimized ...

Electron‐Phonon Interactions Facilitating Large Polaron‐Related Charge‐Carrier Dynamics for Efficient Perovskite Nanocrystal Solar Cells

open access: yesAdvanced Science, EarlyView.
We developed a custom‐synthesized ligand, 2‐thiophenepropenammonium iodide, to exchange the native ligands capped on inorganic perovskite nanocrystals (NCs), and identified that the significantly decreased strength of electron‐phonon interaction benefited the charge‐carrier dynamics in their assembled films.

Electronic Modulation of K⁺‐Intercalated Polymeric Carbon Nitride via ─C≡N/─OH Functionalization for Efficient Photocatalytic H2O2 Production

open access: yesAdvanced Science, EarlyView.
K+ is successfully embedded in the PCN interlayers via a high‐temperature polymerization. The incorporation of K+ perturbs the local electronic structure via interaction with nitrogen lone pairs, narrowing the PCN bandgap, which exhibits superior photocatalytic performance, achieving a high H2O2 generation rate both in situ and under sunlight ...

Tailoring Intermediate Adsorption Through d‐band Mismatch Strategy of Heterojunction to Achieve Industrial Overall Water Splitting

open access: yesAdvanced Science, EarlyView.
This paper demonstrates the fabrication of a Ni3Mo/Ni3N junction to investigate d‐band engineering and elucidate the specific roles of Ni3Mo and Ni3N active sites in improving catalytic activity. Through integrated spectroscopic characterization and first‐principles modeling, for the first time, a d‐band mismatch mechanism has been proposed to ...
