Single Atom‐Particle Tandem Catalysis Enables Enhanced Desolvation Kinetics for Low‐Temperature Li‐S Batteries

open access: yesAdvanced Functional Materials, EarlyView.
In this work, the tandem catalyst consisted of single Fe atom and Fe3C nanoparticles on porous carbon sheet is initially proposed and developed to facilitate the dissociation of Li(solvent)x+ to release more isolated Li+ to participate in the subsequent polysulfide redox conversions by decreasing the related barriers, contributing to fast kinetics of ...

Cu‐Based MOF/TiO2 Composite Nanomaterials for Photocatalytic Hydrogen Generation and the Role of Copper

open access: yesAdvanced Functional Materials, EarlyView.
HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

Crossover Effects of Transition‐Metal Ions on Lithium‐Metal Anode in Localized High Concentration Electrolytes

open access: yesAdvanced Functional Materials, EarlyView.
This study highlights the impact of transition‐metal (TM) ions (Ni2⁺, Mn2⁺, Co2⁺) on the performance of lithium‐metal anode in localized high‐concentration electrolytes. Mn2⁺ and Co2⁺ destabilize SEI and CEI layers, causing capacity fade and overpotential, while Ni2⁺ shows minimal effects. These findings underscore the need for electrolyte optimization
