Abstract

Nitrogen-doped multiwalled carbon nanotubes (CNx-MWNTs) have been decorated with γ-Al₂O₃ nanoparticles by a novel method. This process involved a wet chemical approach in conjunction with thermal treatment. During the particle anchoring process, individual CNx-MWNT nanotubes agglomerated into bundles, resulting in arrays of aligned CNx-MWNT coated with γ-Al₂O₃. Extensive characterization of the resulting γ-Al₂O₃/CNx-MWNT bundles was performed using a range of electron microscopy imaging and microanalytical techniques. In conclusion, a possible mechanism explaining the nanobundle alignment is described, and possible applications of these materials for the fabrication of ceramic composites using CNx-MWNTs are briefly discussed.

Facile synthesis of multifunctional multiwalled carbon nanotubes/Fe{sub 3}O{sub 4} nanoparticles/polyaniline composite nanotubes

Journal Article Kong, Lirong ; Xiaofeng, Lu ; Zhang Wanjin - Journal of Solid State Chemistry

With an average diameter of 100-150 nm, composite nanotubes of polyaniline (PANI)/multiwalled carbon nanotubes (MWNTs) containing Fe{sub 3}O{sub 4} nanoparticles (NPs) were synthesized by a two-step method. First, we synthesized monodispersed Fe{sub 3}O{sub 4} NPs (d=17.6 nm, {sigma}=1.92 nm) on the surface of MWNTs and then decorated the nanocomposites with a PANI layer via a self-assembly method. SEM and TEM images indicated that the obtained samples had the morphologies of nanotubes. The molecular structure and composition of MWNTs/Fe{sub 3}O{sub 4} NPs/PANI nanotubes were characterized by Fourier transform infrared spectra (FTIR), energy dispersive X-ray spectrometry (EDX), X-ray photoelectron spectra (XPS), X-raymore »« less

Fullerene (C{sub 60}) decoration in oxygen plasma treated multiwalled carbon nanotubes for photovoltaic application

Journal Article Kalita, Golap ; Adhikari, Sudip ; Aryal, Hare Ram ; ... - Applied Physics Letters

Multiwalled carbon nanotubes (MWNTs) were functionalized by oxygen plasma treatment. Photoelectron spectroscopy study of oxygen plasma treated MWNTs (O-MWNTs) shows surface modification with hydroxyl and carboxyl groups. C{sub 60} decoration of MWNTs were carried out by thermal evaporation and more dense distribution of C{sub 60} was achieved on O-MWNTs. C{sub 60} decorated MWNTs were combined with poly(3-octylthiophene) for photovoltaic device fabrication. The device with C{sub 60} decorated O-MWNTs shows short circuit current density (J{sub sc}), open circuit voltage (V{sub oc}), fill factor, and power conversion efficiency ({eta}) as 1.68 mA/cm{sup 2}, 0.245 V, 27%, and 0.11%, respectively.

Electromagnetic and microwave-absorbing properties of magnetite decorated multiwalled carbon nanotubes prepared with poly(N-vinyl-2-pyrrolidone)

Journal Article Zhao, Chunying ; Zhang, Aibo ; Zheng, Yaping ; ... - Materials Research Bulletin

Graphical abstract: The Fe{sub 3}O{sub 4}/MWNTs hybrids prepared with PVP achieve a maximum reflection loss is -35.8 dB at 8.56 GHz, and the bandwidth below -10 dB is more than 2.32 GHz. More importantly, a new reflection loss peak occurs at the frequency of 14.6 GHz, which indicates that the Fe{sub 3}O{sub 4}/MWNTs hybrids have better absorption properties in the high-frequency range. Highlight: Black-Right-Pointing-Pointer The Fe{sub 3}O{sub 4} decorated MWNTs hybrids were prepared using PVP as dispersant. Black-Right-Pointing-Pointer Many more Fe{sub 3}O{sub 4} particles were attached homogeneously on the surface of MWNTs.

In situ growth rate measurements and length control during chemical vapor deposition of vertically aligned multiwall carbon nanotubes

Journal Article Geohegan, David B ; Puretzky, Alexander A ; Ivanov, Ilia N ; ... - Applied Physics Letters

Time-resolved reflectivity is employed as an in situ diagnostic in thermal chemical vapor deposition of vertically aligned arrays of multiwall carbon nanotubes (VAA-MWNT). Fabry-Perot interference fringes and attenuation of a reflected HeNe laser beam are used to measure the length of VAA-MWNT throughout the first 3-8 {mu}m of growth yielding in situ measurements of growth rates and kinetics and the capability to observe the onset and termination of growth. VAA-MWNT growth is characterized between 565 and 750 {sup o}C on Si substrates with evaporated Al/Fe/Mo multilayer catalysts and acetylene feedstock. Nanotube lengths were controlled by rapid evacuation of the chambermore »« less

Clean Nanotube Unzipping by Abrupt Thermal Expansion of Molecular Nitrogen: Graphene Nanoribbons with Atomically Smooth Edges

Journal Article Sumpter, Bobby G ; Meunier, Vincent ; Terrones, M. ; ... - ACS Nano

We report a novel physicochemical route to produce highly crystalline nitrogen-doped graphene nanoribbons. The technique consists of an abrupt N2 gas expansion within the hollow core of nitrogen-doped multiwalled carbon nanotubes (CNx-MWNTs) when exposed to a fast thermal shock. The multiwalled nanotube unzipping mechanism is rationalized using molecular dynamics and density functional theory simulations, which highlight the importance of open-ended nanotubes in promoting the efficient introduction of N2 molecules by capillary action within tubes and surface defects, thus triggering an efficient and atomically smooth unzipping. The so-produced nanoribbons could be few-layered (from graphene bilayer onward) and could exhibit both crystallinemore »« less
