ABSTRACT Carbon electrocatalyst materials based on lignocellulosic biomass with multi‐components, various dimensions, high carbon content, and hierarchical morphology structures have gained great popularity in electrocatalytic applications recently. Due to the catalytic deficiency of neutral atoms, usage single lignocellulosic‐based electrocatalysis involving energy storage conversion presents unsatisfactory applicability. However, atomic‐level modulation lignocellulose‐based can optimize electronic structures, charge separation, transfer processes, so forth, which results substantially enhanced performance carbon‐based catalysts. This paper reviews recent advances rational design as electrocatalysts from an perspective, such self/external heteroatom doping metal modification. Then, through systematic discussion principles reaction mechanisms catalysts, prepared catalysts rechargeable batteries are reviewed. Finally, challenges improving prospects diverse review contributes synthesis strategy via modulation, turn promotes lignocellulose valorization for conversion.

Abstract Leveraging economically viable plant bio‐waste‐derived hard carbon (HC) anode materials for sodium‐ion batteries is logical. Many plants' bio‐waste are used as HC precursors, but their fabrication process usually limited by direct carbonization which constrains large‐scale sustainability. Herein, the critical role of pre‐hydrothermal effect in regulating structure and interfacial Na + storage mechanism/performance derived from oak leaves (OL) biowaste (OLHC) reported. The resultant OLHC demonstrates a high‐reversible capacity (378 mAh g −1 at 0.1 C), superior rate performance (272.9 10 remarkable cycling (75% after 8000 cycles adequate ICE (85%). Advanced ex/in situ characterization combined with theoretical calculations reveals that hydrothermal pre‐regulation stabilizes spherical particles, introducing more active sites promoting surface properties oxygen dopant‐induced defects, shows uneven electrostatic potential lower activation energy adsorption thus generates thin layer PF 6 − /NaF‐enriched core‐shell‐like SEI modulation organic–inorganic composition. This enables fast diffusion kinetics, contributing to high‐capacity retention stable performance. studies offer systematic understanding strategy structural design plant‐leaves‐biowaste true sustainability improved SIBs.

The active hydroxyl group of cellulose plays a crucial role in regulating the microstructure cellulose-derived hard carbon, which ultimately affects its sodium storage capacity. Through small-angle X-ray scattering (SAXS) and atomic pair distribution function (PDF) analysis, we proved that modification by esterification crosslinking can introduce more closed pores into carbonized is beneficial for promoting ion storage. Our results demonstrate optimizing conditions used cross-linking modification, capacity carbon could be increased from 254 to 348 mAh g−1, with an increase plateau 140 230 g−1. This study makes significant contribution towards establishing industrial applications carbon.

Nanoscale, Год журнала: 2025, Номер unknown

Опубликована: Янв. 1, 2025

Pitch-derived hard carbon materials are considered one of the most promising anodes for sodium-ion batteries (SIBs) due to their low cost and high yields. However, they largely limited by inferior specific capacity rate capability, resulting from easy graphitization pitch precursor during high-temperature carbonization. Herein, a simple bromination modification coupled with pyrolysis strategy was proposed fabricate pitch-derived (BHC-x), aiming engineer microstructure optimize electrochemical performance SIBs. The detailed experimental investigations demonstrated that brominated obtained via hydrothermal treatment underwent cross-linking polycondensation in presence bromine species at 350 °C, thereby forming unique disordered closed structure process. As result, optimized BHC-1500, rich defect sites suitable interlayer spacing 0.358 nm, exhibited reversible 250.0 mA h g-1 0.1 A an initial coulombic efficiency (ICE) 79.8%. It still maintained 150.0 5 g-1, outperforming unbrominated counterparts (152.1 g-1). This work proposes new insights into optimization pitch-based high-performance
