Ternary Synergy in Layered Double Hydroxides for Efficient and Stable Nitrate Reduction

open access: yesAdvanced Functional Materials, EarlyView.
Ternary CuZnFe LDH enables efficient electrocatalytic nitrate‐to‐ammonia conversion via controlled in situ reconstruction: zinc leaching creates porous active sites, copper reduced to metallic copper, while iron oxide keeps stable. Synergistic Cu‐Fe redox coupling drives tandem catalysis (nitrate→nitrite→NH3), achieving 95% Faraday efficiency and ...

Fine‐Tunning BaCo0.4Fe0.4Zr0.1Y0.1O3−δ‐Based Air Electrodes for Reversible Protonic Ceramic Cells via Co‐Engineering A‐site Deficiency and Nickel Content

open access: yesAdvanced Functional Materials, EarlyView.
A synergistic strategy combining A‐site deficiency and B‐site nickel doping yielded a BCFZYN‐095‐01 nanocomposite air electrode for reversible protonic ceramic cells with superior ORR/OER activities. B‐site deficiency in the perovskite lattice enhances proton conduction, and nickel doping within the bulk facilitates oxygen transport.

Heterostructured Sn:SnO2 Nanodots for High‐Performance Li–S Batteries with Kinetics‐Enhanced Cathode and Dendrite‐Free Anode

open access: yesAdvanced Functional Materials, EarlyView.
Heterostructured Sn:SnO2 nanodots decorated on reduced graphene oxide can simultaneously enhance conversion kinetics and inhibit dendrite growth, enabling stable lithium–sulfur batteries. Abstract The practical application of lithium–sulfur batteries is limited by polysulfide shuttling and sluggish reaction kinetics at the cathode, as well as ...

Graft Copolymer‐Stabilized Liquid Metal Nanoparticles for Lithium‐Ion Battery Self‐Healing Anodes

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a self‐healing liquid metal anode for lithium‐ion batteries, where graft copolymer‐stabilized eutectic gallium indium (EGaIn) nanoparticles enhance stability and rate performance. The fluorinated grafted copolymer forms ionic channels, preventing EGaIn aggregation and facilitating lithium‐ion migration.
