Synergistic Fe–Si Dual‐Site Pathway Engineering in Biomass‐Derived Carbon Matrix for High‐Performance Oxygen Reduction Reaction

Carbon Energy, EarlyView.
We report a dual‐atomic Si–Fe–N–C catalyst synthesized from nitrogen‐rich pinecones and an Fe porphyrin precursor. The inherent Si and N in pinecones form a porous Si–N–C framework that stabilizes Fe atoms during pyrolysis, yielding robust Si–Fe dual sites.

Spin‐State Engineering via Cr3+ Incorporation in Co3O4 Spinel for Efficient Bifunctional Oxygen Electrocatalysis

Carbon Energy, EarlyView.
Cr doping causes distortion of the CoO6 octahedron, modifies the spin state of CoOh, and enhances the bifunctional catalytic activity. ABSTRACT The primary challenge in rechargeable Zn‐air batteries lies in developing a catalyst capable of simultaneously improving performance for oxygen reduction reaction (ORR) during discharge and oxygen evolution ...

Interfacial Ru–O–W Orbital Coupling Enables Lattice Oxygen Stabilization for Enhanced Acidic OER

Carbon Energy, EarlyView.
A RuO2/WO3 electrocatalyst with strong interfacial Ru–O–W bonds exhibits optimized Ru–O interactions, enhancing intrinsic activity and stability for acidic OER. The WO3 support modulates the electronic structure of RuO2 and promotes oxo‐intermediate deprotonation, delivering a low overpotential of 203 mV at 10 mA cm−2 and sustained operation beyond 200
