“…Four different armchair-type SWNTs [(4, 4), (8,8), (12,12), and (16,16)] are considered here. Our simulation results show that both EA + cations and NO 3 − anions can form a cylindrical double-shell solvation structure around the SWNTs regardless of the nanotube diameter.…”

Molecular dynamics simulations have been performed to explore the solvation structures and vibrational spectra of an ethylammonium nitrate (EAN) ionic liquid (IL) around various single-walled carbon nanotubes (SWNTs). Our simulation results demonstrate that both cations and anions show a cylindrical double-shell solvation structure around the SWNTs regardless of the nanotube diameter. In the first solvation shell, the CH 3 groups of cations are found to be closer to the SWNT surface than the NH 3 + groups because of the solvophobic nature of the CH 3 groups, while the NO 3 − anions tend to lean on the nanotube surface, with three O atoms facing the bulk EAN. On the other hand, the intensities of both C−H (the CH 3 group of the cation) and N−O (anion) asymmetric stretching bands at the EAN/SWNT interface are found to be slightly higher than the corresponding bulk values owing to the accumulation and orientation of cations and anions in the first solvation shell. More interestingly, the N−O stretching band exhibits a red shift of around 10 cm −1 with respect to the bulk value, which is quite contrary to the blue shift of the O−H stretching band of water molecules at the hydrophobic interfaces. Such a red shift of the N−O stretching mode can be attributed to the enhanced hydrogen bonds (HBs) of the NO 3 − anions in the first solvation shell. Our simulation results provide a molecular-level understanding of the interfacial vibrational spectra of an EAN IL on the SWNT surface and their connection with the relevant solvation structures and interfacial HBs.

“…Nanocomposites with different IL contents were obtained by interactions between IL and multiwalled carbon nanotubes (MWCNTs) [35]. Ding et al proposed that instead of a cation-π interaction, the main interaction would be a CH-π hydrogen bond, in which the CH in the position 2 of the IL imidazolium cation acts as proton donor and the π bonds in the carbon nanotubes act as proton acceptors (see Figure 3).…”

Ionanocarbon Lubricants. The Combination of Ionic Liquids and Carbon Nanophases in Tribology

et al. 2017

View full text Add to dashboard Cite

The present overview will focus on the tribological applications of what we have called ionanocarbon lubricants, that is, the combination of carbon nanophases (graphene, carbon nanotubes, nanodiamonds, carbon nanodots) and room-temperature ionic liquids in new dispersions, blends, or modified nanostructures and their use in tribology, lubrication, and surface engineering as friction-reducing, antiwear, and surface-protecting agents in thin films and composite materials. Further research lines and factors that limit the practical applications of the outstanding research results are also highlighted. The very recent results in these lines of research make this a necessary brief review.

“…The chemical bonding between the PIL and the CNT anchors the PIL on the CNT and enhances the conductivity of the whole system. The π bonds coupling the CNTs and the PIL supply multiple binding centers and can also enhance the noncovalent interactions between polymerized IL and the CNT surfaces 12a. The as‐obtained nanocomposites contain a uniform PIL coating and evenly distributed Co species on the CNT surfaces.…”

By taking inspiration from the catalytic properties of single‐site catalysts and the enhancement of performance through ionic liquids on metal catalysts, we exploited a scalable way to place single cobalt ions on a carbon‐nanotube surface bridged by polymerized ionic liquid. Single dispersed cobalt ions coordinated by ionic liquid are used as heterogeneous catalysts for the oxygen evolution reaction (OER). Performance data reveals high activity and stable operation without chemical instability.
