Abstract Ferrous sulfides with the high theoretic capacity are promising anode for sodium ion batteries. However, fading and inferior rate capability still hinder their practical application. In this work, Na‐doped Fe 7 S 8 microrods cationic vacancies weakened Fe─S bond constructed through a facile scalable sulfurized route. The experimental results combined theoretical analysis thoroughly reveal generation of strength induced by doping, which modulates energy band structure , provides more active sites, accelerates sodiation/desodiation reaction kinetics, simultaneously. Moreover, pre‐doping delivers strong guiding effect on formation thin stable solid electrolyte interface films. As result, optimal sample exhibits excellent storage performance, including reversible (674 mAh g −1 after 200 cycles at 0.5 A 503 1500 10 ), superior capability, increased initial coulombic efficiency. Furthermore, full cell paired commercial Na 3 V 2 (PO 4 ) also displays outstanding cyclic stability 95.9% retention 100 cycles.

Surface Phosphorus Grafting of Ti₃C₂T_x MXene as an Interface Charge “Bridge” for Efficient Electrocatalytic Hydrogen Evolution in All-pH Media

Chemistry of Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 4, 2024

The interface electronic structure of heterogeneous catalysts can be modulated by changing the surface coordination configuration, which is crucial to their catalytic activity. Herein, a phosphorus-grafted Ti3C2Tx MXene platform anchored with an MoS2 nanoflake heterojunction electrocatalyst was assembled through simple phosphorus-hydrothermal method. An charge "bridge" has been created grafting uniform P atoms coordinated O (P-Ti3C2Tx), resulting in charge-transfer channel between P-Ti3C2Tx and MoS2. Based on ultrafast transient absorption spectroscopy, fastest electron-transfer kinetics from (1.7 ps) slowest electron–hole recombination speed (28 were obtained over MoS2@P-Ti3C2Tx than those MoS2@O-Ti3C2Tx MoS2@OP-Ti3C2Tx. Benefiting lower carrier transport activation energy, exhibited stirring electrocatalytic activity toward hydrogen evolution all-pH media, delivered three low overpotentials 48.6, 63.2, 70.5 mV at 10 mA cm–2 alkaline, acid, neutral respectively. Grafting atomic scale create proposes new strategy design efficient pH-universal electrocatalyst.
