Low‐Temperature Exsolution of Cobalt From Perovskite Nanoparticles via Bead Milling for Enhanced Electrocatalytic Oxygen Evolution Reaction

Advanced Functional Materials, EarlyView.
High‐temperature requirements and complex synthesis limit the practical use of perovskite‐based metal exsolution catalysts. This study addresses these limitations by employing bead milling, enabling efficient metal exsolution at a significantly lower temperature (300 °C) from La0.6Sr0.4CoO3‐δ nanoparticles. Consequently, the catalytic mass activity for

Molecular‐Level Dual‐Ionophilic Passivation for High‐Areal‐Capacity Lithium Metal Anodes on Nanostructured Paper Electrodes

Advanced Functional Materials, EarlyView.
The effect of a molecular‐level dual‐ionophilic chitosan passivation layer is investigated on a nanostructured paper electrode featuring an interconnected network structure of highly oxygen‐functionalized single‐walled carbon nanotubes (C‐NPE). This molecular coating enabled a high Coulombic efficiency (>99.0%) and stable cycling over 350 cycles at an ...
