“…Because of high electron affinity, high carrier mobility, low reorganization energy, and optical properties, fullerenes have been considered to be a promising nanocarbon material in a wide variety of applications such as solar cells, field-effect transistors, catalysts, and biological tools . Another utility of fullerenes is their attractive interactions with various organic, − organometallic, and inorganic − species as well as biomolecules − based on π−π, van der Waals, and donor−acceptor interactions. Such attractive forces allow fullerenes and their derivatives to adsorb chemical compounds at a certain strength, and fullerenes have been considered to be peculiar candidates for use in chromatographic stationary phases, extraction tools, and adsorbents. − …”

Selective Formation and Structural Properties of Rhombic Dodecahedral [70]Fullerene Microparticles Formed by Reaction with Aliphatic Diamines

2009

We have accomplished the selective formation of rhombic dodecahedral microparticles on the submicrometer to micrometer scale by the reaction of [70]fullerene (C(70)) with primary aliphatic diamines. The morphology of the resultant microparticles was analyzed by scanning electron microscopy, powder X-ray diffraction, and other spectroscopic methods, demonstrating that the resultant particles held a rhombic dodecahedral shape having a simple cubic lattice structure and that primary aliphatic amines were mostly trapped inside the particles through electronic interaction between C(70) and amines. Furthermore, we have discovered interesting structural characteristics in which the incorporated amines could be removed from the C(70) microparticles or exchanged with other primary aliphatic diamines.

Investigation of carbon graphite-like structures by laser mass spectrometry

et al. 2012

View full text Add to dashboard Cite

Sorbents prepared from industrial waste and some carbon graphite like materials are studied by laser ablation and time of flight mass spectrometry. The mass spectra of all materials show a peak at a mass of 465 u. This peak is found to correspond to a molecule of mass 426 u to which a K + ion is attached. An expo nential dependence of the M = 465 u peak intensity on the sorbent specific surface area in the range from 20 to 1200 m 2 /g is obtained.

“…This indicates that the above O 1s XPS peaks are related to oxygen and water molecules physically adsorbed on the surfaces of C 60 and HOPG without the formation of an oxygen-carbon chemical bond. Numerous studies of the adsorption of oxygen compounds on the surfaces of C 60 fullerite powder and films [35,[56][57][58][59][60] showed that at temperatures below 470 K water molecules from the air are physically adsorbed and remain on the surface even under high vacuum conditions. Since in our experiments, investigation was carried out at room temperature, most likely, there was a physical adsorption of water molecules.…”

The Formation of Nanoscale Closed Graphene Surfaces during Fullerite C60 Hot Isostatic Pressing

et al. 2021

View full text Add to dashboard Cite

The fullerite C60 modified by hot isostatic pressing (HIP) at 0.1 GPa in argon near and beyond its thermal stability region (920–1270 K temperature interval) was studied by X-ray diffractometry, Raman spectroscopy, ultra soft X-ray photoelectron and near edge X-ray absorption fine structure spectroscopy. It was found that the C60 molecules merge into closed nanocapsules with a graphene surface during the thermal treatment. The conducted studies showed that using HIP treatment of the fullerite C60, it is possible to obtain a chemically resistant material with a high hardness and elasticity, as well as a density lower than that of the graphite. This new material, consisting of closed graphene nanocapsules 2–5 nm in size, formed by sp2 covalent bonds between carbon atoms is promising for various applications, and as a basis for the synthesis of new composite materials.
