Tunable Interfacial Electric Field‐Mediated Cobalt‐Doped FeSe/Fe₃Se₄ Heterostructure for High‐Efficiency Potassium Storage

Angewandte Chemie International Edition, Journal Year: 2024, Volume and Issue: 63(28)

Published: April 25, 2024

Abstract The interfacial electric field (IEF) in the heterostructure can accelerate electron transport and ion migration, thereby enhancing electrochemical performance of potassium‐ion batteries (PIBs). Nevertheless, quantification modulation IEF for high‐efficiency PIB anodes currently remains a blank slate. Herein, we achieve first time tuning via amorphous carbon‐coated undifferentiated cobalt‐doped FeSe/Fe 3 Se 4 (denoted UN‐CoFe 5 /C) efficient potassium storage. Co doping increase , improving transport, promoting adsorption capacity, lowering diffusion barrier. As expected, magnitude /C is experimentally quantified as 62.84 mV, which 3.65 times larger than that (Fe /C). Benefiting from strong IEF, anode exhibits superior rate capability (145.8 mAh g −1 at 10.0 A ) long cycle lifespan (capacity retention 95.1 % over 3000 cycles 1.0 ). Furthermore, this strategy universally regulate CoSe 2 /Co 9 8 FeS /Fe 7 S heterostructures. This work provide fundamental insights into design advanced electrodes.

ChemSusChem, Journal Year: 2024, Volume and Issue: unknown

Published: June 4, 2024

Abstract Electrocatalytic water splitting shows great potential for producing clean and green hydrogen, but it is hindered by slow reaction kinetics. Advanced electrocatalysts are needed to lower the energy barriers. The establishment of built‐in electric fields (BIEF) in heterointerfaces has been found be beneficial speeding up electron transfer, increasing electrical conductivity, adjusting local environment, optimizing chemisorption with intermediates. Engineering modifying BIEF heterojunctions offer significant opportunities enhance electronic properties catalysts, thus improving This comprehensive review focuses on latest advances engineering heterojunction catalysts efficient electrolysis. It highlights fundamentals, engineering, modification, characterization, application electrocatalytic splitting. also discusses challenges future prospects engineering.
