摘要

过渡金属/多孔碳复合材料是很好的电极候选材料，因为多孔碳提供了高表面孔隙率，促进了电解质离子的进入，而过渡金属可以进行氧化还原反应，提高比电容和能量密度。本研究采用静电纺丝和聚丙烯腈（PAN）热处理法制备了铁/碳纳米纤维（CNF）复合电极，并将二茂铁甲醛接枝到CNF上。通过SEM/EDS、ICP-MS和XPS等手段证实了CNF表面存在铁元素。以1 M Na2SO4为电解液，采用三电极电池对电化学性能进行了评价。铁接枝CNFs在0.5 a g−1下的比电容为358 F g−1，能量密度为49.7 Wh kg−1，显著高于未处理的CNFs （68 F g−1和9.4 Wh kg−1）。这表明这种铁/CNF复合材料具有优异的储能性能，是超级电容器电极的理想候选材料。

Preparation of iron/carbon composite by grafting ferrocene to carbon nanofibers for supercapacitor electrodes

Transition metal/porous carbon composite is good electrode candidate since porous carbon provides high surface porosity which promotes the access of electrolyte ions, and transition metal enables redox reactions to improve specific capacitance and energy density. In this study, iron/carbon nanofiber (CNF) composite electrodes were prepared by grafting ferrocenecarboxaldehyde to the CNFs which were fabricated by electrospinning and thermal treatment of polyacrylonitrile (PAN). The presence of iron on the CNF surface was confirmed by SEM/EDS, ICP-MS and XPS. Electrochemical performance was evaluated using a three-electrode cell with 1 M Na₂SO₄ as an electrolyte. Iron-grafted CNFs exhibited a high specific capacitance of 358 F g⁻¹ and an energy density of 49.7 Wh kg⁻¹ at 0.5 A g⁻¹, which is significantly higher than those for untreated CNFs (68 F g⁻¹ and 9.4 Wh kg⁻¹). This demonstrates that this iron/CNF composite is promising candidate for supercapacitor electrode with outstanding energy storage performance.

期刊介绍： Carbon Letters aims to be a comprehensive journal with complete coverage of carbon materials and carbon-rich molecules. These materials range from, but are not limited to, diamond and graphite through chars, semicokes, mesophase substances, carbon fibers, carbon nanotubes, graphenes, carbon blacks, activated carbons, pyrolytic carbons, glass-like carbons, etc. Papers on the secondary production of new carbon and composite materials from the above mentioned various carbons are within the scope of the journal. Papers on organic substances, including coals, will be considered only if the research has close relation to the resulting carbon materials. Carbon Letters also seeks to keep abreast of new developments in their specialist fields and to unite in finding alternative energy solutions to current issues such as the greenhouse effect and the depletion of the ozone layer. The renewable energy basics, energy storage and conversion, solar energy, wind energy, water energy, nuclear energy, biomass energy, hydrogen production technology, and other clean energy technologies are also within the scope of the journal. Carbon Letters invites original reports of fundamental research in all branches of the theory and practice of carbon science and technology.
