Abstract Hard carbon (HC) materials are suitable anodes for sodium‐ion batteries (SIBs) but still suffer from insufficient initial Coulombic efficiency (ICE). Promoting sodium storage via the pore filling mechanism is an effective way to improve ICE, and key here regulating structures of HC. In this work, coal‐derived HC successfully engineered with abundant accessible closed nanopores by treating coal precursors a facile destructive oxidation strategy. Investigations demonstrate that strategy can not only introduce oxygen‐containing functional groups (OFGs) also decrease size graphitic microcrystals. Thus, OFGs significantly enhance crosslinking small microcrystals stimulate formation during carbonization, which eventually improves ICE promoting mechanism. The optimized exhibits so far highest (92.2%) among SIB anode materials, together considerable capacity 328.5 mAh g −1 at 90 mA retention 95.1% after 150 cycles. results provide guidelines developing high‐performance toward large‐scale application SIBs, great significance future energy systems.

The 1999 discovery of one-pot corrole synthesis opened the floodgates for research on these unique macrocyclic chelating agents. enormous impact this has been documented in numerous reviews describing advances synthetic chemistry corroles and selected applications which are key components. Our silver anniversary review focuses structures reactions all well characterized corrole-chelated d- p-block metal complexes, including discussions their electronic excited-state physics chemistry. Emphasis is placed structure trinegative N4 coordination core, stabilizes high-valent metals activates low-valent ones, and, importantly, profoundly influences ground- reactivity. story highlights properties that have made them molecular components choice a plethora applications. These include utility sensing gases anions, rescue vital biomolecules from oxidative damage, destruction cancerous cells, catalysis critical organic synthesis, as those involved clean energy processes such production hydrogen reduction oxygen. In our view, will continue to grow by leaps bounds, most especially areas human health renewable science technology.
