Electronic Synergy in NiCo‐Embedded Nitrogen‐Doped Hollow Mesoporous Carbon Spheres for Bifunctional Oxygen Catalysis and Zinc–Air Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study employs a hard‐templating etching strategy to synthesize N‐doped hollow mesoporous carbon spheres embedded with NiCo nanoparticles (denoted as NiCo@N‐HMCS). The optimized catalyst exhibits exceptional bifunctional catalytic activity for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) in alkaline media, achieving a ...

Synergistic Regulation of Hierarchical Anode Interphase and Cathode Electronic Structure by a Fe(III) Complex for High‐Performance Aqueous Zinc‐Manganese Battery

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The NGB additive can concurrently address anode and cathode issues during Zn‐Mn battery cycling by constructing a hierarchical interfacial layer on the anode surface to alleviate side reactions and modulate zinc deposition and by incorporating Fe3+ ions into the α‐MnO2 cathode to improve its structural stability and electrical conductivity.
