A Proton‐Intercalation Pathway Realizes Long‐Life Manganese‐Ion Hybrid Batteries With Layered KV3O8

open access: yesAdvanced Science, EarlyView.
This is the first study to demonstrate layered monoclinic KV3O8 as a highly stable cathode material for aqueous Mn‐based hybrid batteries, exhibiting excellent cycling stability with 88.0% capacity retention after 3600 cycles. The proton storage mechanism is systematically elucidated through comprehensive spectroscopic analyses, further supported by ...

Stabilizing Atomically Dispersed Au With Adjacent Pt for Spatially Precise Molecule Recognition

open access: yesAdvanced Science, EarlyView.
A strategy to stabilize atomically dispersed Au catalysts by introducing Pt atoms into CeO2 supports is presented. Pt incorporation prevents Au aggregation, enhances Au‐O orbital coupling, and enables precise recognition of multi‐functionalized molecules, improving catalytic performance and the structural stability of Au‐based catalysts in ...
