Facilitating Sodium‐Ion Diffusion in Fe‐Doped Co3O4 for High‐Rate Performance

open access: yesSmall, EarlyView.
The limited rate performance of cobalt oxide (Co3O4) materials restricts their applicability in the rapid charge–discharge process of sodium‐ion batteries (SIBs). Iron (Fe) lattice doping can facilitate sodium‐ion diffusion by narrowing the bandgap and modulating the Co─O bond length.

Cobalt Borate Complex With Tetrahedrally Coordinated Co2+‐ Promotes Lithium Superoxide Formation in Li‐O2 Batteries

open access: yesSmall, EarlyView.
This study investigates sodium cobalt borate (Na3CoB5O10, NCBO) as an oxygen electrocatalyst for non‐aqueous lithium‐oxygen (Li‐O2) batteries. NCBO exhibits favorable oxygen evolution reaction activity with a low overpotential and enhanced stability in Li‐O2 cycling.

3D Lithiophilic Freestanding Hosts with SiOx‐Embedded Hierarchical Porous N‐Doped Carbon Nanofibers for Dendrite‐Free Lithium Metal Batteries

open access: yesSmall, EarlyView.
Herein, SiOx@PCNFs are synthesized by electrospinning process with subsequent thermal treatment. The SiOx@PCNFs showed tubular pores made by PS and HNC originating from ZIF‐8. The pore structures of these samples provided internal spaces for Li deposition while the optimized electrical conductivity is provided by conductive CNFs and insulative SiOx for

Defective Antifluorite MnO2‐Layered RuO2 for Direct Seawater Electrolysis at Circum‐Neutral pH

open access: yesSmall, EarlyView.
A defective antifluorite MnO2 overlayer that enables nearly 100% oxygen selectivity in direct seawater electrolysis at neutral pH is reported. Combining experimental validation and DFT simulations, this work reveals how a unique Mn–O framework blocks chloride while maintaining OER activity—offering a robust and scalable solution for green hydrogen ...

Precisely Controlled Integration of Multiple Metal Cations in Diverse Metal‐Organic Framework Topologies via Messenger Building Unit Approach

open access: yesSmall Structures, EarlyView.
Heterometallic molecular clusters used as messenger building units yield metal‐organic frameworks (MOFs) with distinct topologies through the combination with selected linkers of various connectivities. Specific metal combinations are thus precisely inserted in MOFs, enhancing their performance as heterogeneous photocatalysts after being structured in ...
