Transition Metal Slab Gliding: One Key Process for Activating Anionic Redox Reaction in P2‐Type Transition Metal Oxide Cathodes

open access: yesAdvanced Science, EarlyView.
Transition metal (TM) slab gliding is a key process for activating anionic redox reaction in P‐type layered oxide materials. Disordered TM layer weakens interlayer interactions and facilitates TM slab gliding. The resulting O‐type layer promotes reversible TM migration, provides the necessary Na–O–□TM configuration, and activates anionic redox reaction.

Overcoming the Low‐Temperature Barrier: Controlling Li₂S Deposition and Enhancing Catalysis in Lithium‐Sulfur Batteries Using Island‐like Bi₂O₃ on rGO

open access: yesAdvanced Science, EarlyView.
A new island‐like Bi₂O₃ uniformly distributed on the reduced graphene oxide (IBG) is synthesized as a sulfur host material. IBG's special targeted catalytic ability toward two rate‐determining steps at low temperatures. IBG enhances catalytic efficiency at low temperatures, preventing Li₂S accumulation and improving charge–discharge efficiency ...

Transforming the Poison Effects of Water Vapor into Benefits Over Adjustable Dual Acid Sites for Stable Plasma‐Catalysis

open access: yesAdvanced Science, EarlyView.
YxMnyOx+2y catalyst provides dual active sites of Lewis acid (Y3+) and Mn for the co‐adsorption of H2O and O3, and the fast dissociation of adsorbed H2O to surface *OH. Then, a newly OH‐accompanied pathway for O3 decomposition is formed, transforming H2O to active ·OH radical, with the assistance of high energy electrons in the plasma.
