“…Lee et al was first to report coating CNFs via ALD as they successfully coated bamboo-type nanofibers with Al 2 O 3 using trimethylaluminum and distilled water. 101 They demonstrated uniform and controlled growth of amorphous Al 2 O 3 on the outside of the fibers and also demonstrated that the interior cavities of the fibers could also be coated to varying degrees. Later, Herrmann et al also coated CNTs with Al 2 O 3 and Al 2 O 3 / W bilayer via ALD.…”

“…ALD has been used by a few research groups to coat CNTs and CNFs. [99][100][101] ALD is particularly suited for coating large area and high aspect ratio structures because it allows atomic layer thickness control over an entire surface by a sequence of self-limiting reactions. Lee et al was first to report coating CNFs via ALD as they successfully coated bamboo-type nanofibers with Al 2 O 3 using trimethylaluminum and distilled water.…”

Carbon nanofibers are high-aspect ratio graphitic materials that have been investigated for numerous applications due to their unique physical properties such as high strength, low density, metallic conductivity, tunable morphology, chemical and environmental stabilities, as well as compatibility with organochemical modification. Surface studies are extremely important for nanomaterials because not only is the surface structurally and chemically quite different from the bulk, but its properties tend to dominate at the nanoscale due to the drastically increased surface-to-volume ratio. This review surveys recent developments in surface analysis techniques used to characterize the surface structure and chemistry of carbon nanofibers and related carbon materials. These techniques include scanning probe microscopy, infrared and electron spectroscopies, electron microscopy, ion spectrometry, temperature-programed desorption, and atom probe analysis. In addition, this article evaluates the methods used to modify the surface of carbon nanofibers in order to enhance their functionality to perform across an exceedingly diverse application space.

“…One is a sol-gel method using tetraethoxysilane (TEOS) [36]. The other is atomic-layer deposition using trimethylaluminum (TMA) [37]. However, to date, a method for precise control of the thickness and stoichiometry of insulator-coated CNTs has not been established.…”

In this review, we demonstrate the device-oriented synthesis of carbon nanotubes (CNTs), by taking an energy storage device and a field electron emitter as examples. As one of the most desirable approaches to fabricating nanostructured hybrids between carbon nanotubes and inorganic materials, we present a method of coating carbon nanotubes with inorganic materials in multishell form, and its application to nanoprobe fabrication.

“…Several routes have been reported for the synthesis of nanostructured materials including hydrothermal, [3][4][5][6][7][8][9][10][11][12][13] solgel, [14][15][16][17] anodisation, [18][19][20] atomic layer deposition 21 and wet etching. 22 Amongst these, hydrothermal methods are popular as they are cheap, reproducible, simple and can be easily scaled up.…”

γ-Al₂O₃nanorods with tuneable dimensions – a mechanistic understanding of their hydrothermal synthesis

et al. 2017

This paper reports for the first time the size control of well-defined and morphologically pure alumina (gAl 2 O 3 ) nanorods, presenting an economic and reproducible route for the manufacture of these materials with tuneable sizes for useful applications, for example serving as adsorbents, catalysts and catalyst supports. A detailed understanding of the different steps taking place during the hydrothermal synthesis has been deduced herein. Understanding the effect of temperature on the relative rates of these steps is essential for achieving size and morphology selectivity, but has often been overlooked in the literature.This systematic study identifies six distinct steps taking place during the synthesis: (1)
