Chemical charging of single-walled carbon nanotubes (SWCNTs) and graphenes to generate soluble salts shows great promise as a processing route for electronic applications, but raises fundamental questions. The reduction potentials of highly-charged nanocarbon polyelectrolyte ions were investigated by considering their chemical reactivity towards metal salts/complexes in forming metal nanoparticles. The redox activity, degree of functionalisation and charge utilisation were quantified via the relative metal nanoparticle content, established using thermogravimetric analysis (TGA), inductively coupled plasma atomic emission spectroscopy (ICP-AES) and X-ray photoelectron spectroscopy (XPS). The fundamental relationship between the intrinsic nanocarbon electronic density of states and Coulombic effects during charging is highlighted as an important area for future research.
将单壁碳纳米管（SWCNT）和石墨烯进行化学充电以生成可溶性盐，作为电子应用的一种加工途径显示出巨大潜力，但也引发了一些基本问题。通过考虑高电荷纳米碳聚电解质离子在形成金属纳米颗粒时对金属盐/配合物的化学反应性，研究了它们的还原电位。通过使用热重分析（TGA）、电感耦合等离子体原子发射光谱（ICP-AES）和X射线光电子能谱（XPS）确定的相对金属纳米颗粒含量，对氧化还原活性、功能化程度和电荷利用率进行了量化。本征纳米碳电子态密度与充电过程中库仑效应之间的基本关系被突出显示为未来研究的一个重要领域。
