Tailor‐Made Protective LixAlSy Layer for Lithium Anodes to Enhance the Stability of Solid‐State Lithium–Sulfur Batteries

open access: yesAdvanced Materials Interfaces, EarlyView.
An intentionally added, chemically formed LixAlSy coating stabilizes the lithium–electrolyte interface in solid‐state Li–S batteries. The layer suppresses side reactions, preserves smooth charge transfer, and improves ion transport from the start. This approach offers a practical route to more durable solid‐state batteries and a clearer understanding ...

Tin Oxide‐Anchored MXene Composites for Enhanced Hydrogen Evolution in Alkaline Media

open access: yesAdvanced Materials Interfaces, EarlyView.
The schematic illustrates a SnO2/MXene heterostructure for efficient hydrogen evolution. SnO2 nanoparticles are uniformly anchored on conductive MXene nanosheets, enhancing charge transfer and catalytic activity. The MXene substrate provides high electrical conductivity and abundant active sites, while SnO2 facilitates water adsorption and dissociation.

Suppressing Metal–Molecule Charge Transfer With a Phosphorus Interlayer

open access: yesAdvanced Materials Interfaces, EarlyView.
Phosphorus forms stable reconstructions with remarkable properties on various metal substrates. Here, using a spectroscopic approach, its role as an effective buffer layer on Cu(110) is demonstrated, preventing charge transfer to adsorbed Zn‐tetraphenylporphyrins (ZnTPP).
