Ultra‐Thick Carbon Microhoneycomb Cathode for High‐Capacity Lithium‐Oxygen Batteries
This work demonstrates ultra‐thick biochar‐derived carbon microhoneycomb cathodes for lithium‐oxygen batteries. The penetrated macrochannels serve as highly efficient pathways for Li+ and O2 and provide abundant accommodation space for the discharge product. The optimized cathode achieved a high areal capacity of 38.2 mAh cm–2, providing guidelines for

ABSTRACT Hard carbon (HC) is currently the predominant anode material for sodium‐ion batteries; however, its practical application is still limited by insufficient initial Coulombic efficiency (ICE) and plateau capacity. Meanwhile, conventional HC production relies on energy‐intensive carbonization processes with considerable carbon emissions. Here, an

Catalyst‐Free Selective Reduction of Nitrogen Dioxide to Nitric Oxide
Common main group reductants selectively convert nitrogen dioxide to nitric oxide in a catalyst‐free manner. Computational studies suggest divergent reaction pathways depending on the reductant employed. Where boranes and silanes proceed via a two‐electron process, and hydrogen surrogates undergo stepwise one‐electron processes.
