Direct transformation of graphene to fullerene.
Although fullerenes can be efficiently generated from graphite in high yield, the route to the formation of these symmetrical and aesthetically pleasing carbon cages from a flat graphene sheet remains a mystery. The most widely accepted mechanisms postulate that the graphene structure dissociates to very small clusters of carbon atoms such as C(2), which subsequently coalesce to form fullerene ...
متن کاملTransport of fullerene molecules along graphene nanoribbons
We study the motion of C₆₀ fullerene molecules and short-length carbon nanotubes on graphene nanoribbons. We reveal that the character of the motion of C₆₀ depends on temperature: for T < 150 K the main type of motion is sliding along the surface, but for higher temperatures the sliding is replaced by rocking and rolling. Modeling of the buckyball with an included metal ion demonstrates that th...
متن کاملGraphene mediated self-assembly of fullerene nanorods.
A simple procedure for solution-based self-assembly of C60 fullerene nanorods on graphene substrates is presented. Using a combination of electron microscopy, X-ray diffraction and Raman spectroscopy, it is shown that the size, shape and morphology of the nanorods can be suitably modified by controlling the kinetics of self-assembly.
متن کاملFullerene-Grafted Graphene for Efficient Bulk Heterojunction Polymer Photovoltaic Devices.
A simple lithiation reaction was developed to covalently attach monosubstituted C60 onto graphene nanosheets. Detailed spectroscopic (e.g., Fourier transform infrared, Raman) analyses indicated that C60 molecules were covalently attached onto the graphene surface through monosubstitution. Transmission electron microscopic (TEM) observation revealed that these monosubstituted C60 moieties acted ...
متن کاملMagnetic properties of all-carbon graphene-fullerene nanobuds.
The magnetic properties of proposed all-carbon graphene-fullerene nanobuds have been investigated through spin-polarized density functional theory. Four structures (A, B, C and D) are proposed in terms of the geometry, and analysis of the formation of new chemical bonds in the nanobuds is conducted. Cases A and B possess magnetic moments of nearly 6 μ(B), originating from unpaired spins due to ...
