Carbon nanomaterials have been extensively used in many applications owing to their unique thermal, electrical and mechanical properties. One of the prime challenges is the production of these nanomaterials on a large scale. This review paper summarizes the synthesis of various carbon nanomaterials via the chemical vapor deposition (CVD) method. These carbon nanomaterials include fullerenes, carbon nanotubes (CNTs), carbon nanofibers (CNFs), graphene, carbide-derived carbon (CDC), carbon nano-onion (CNO) and MXenes. Furthermore, current challenges in the synthesis and application of these nanomaterials are highlighted with suggested areas for future research.

“…The particle size of the catalyst is one of the factors determining the diameter of the synthesized CNTs. For the growth of CNTs, a variety of carbon-containing gases and liquids are used that undergo pyrolysis at synthesis temperatures (500-1200 °C [5][6][7][8][9][10][11][12][13]. In this paper, the synthesis of carbon nanotubes using nickel catalysts supported on the naturally occurring minerals diatomite and shungite is described.…”

In this work, carbon nanotubes were prepared using catalysts consisting of nickel particles supported on the naturally occurring minerals diatomite and shungite. The carbon source for the chemical catalytic vapour deposition (CCVD) synthesis was a propane-butane gas mixture. The synthesized multiwall carbon nanotubes (MWCNT) were characterized using Raman spectroscopy, transmission and scanning electron microscopy, and the effect of temperature on their structure was investigated. The carbon content was determined by thermogravimetric analysis. In Raman spectra of CNTs the intensity ratio I(G)/I(D) for 650 °C is higher than that for 700 °C and then it begins to increase with increasing temperature. The results show that the diameter of CNTs which were synthesized on the surface of diatomite/shungite samples were in the range of 33–100.3 nm. The development of new methods for creating catalytic systems that allow controlling the structure of carbon particles is an important task leading to the improvement of existing approaches to the synthesis of CNTs with certain functional properties.

“…High-quality field emitters are desirable for applications in a wide range of field-emission-based devices such as high brightness electron source, panel displays, microwave amplifiers, and X-ray sources. In recent years, many efforts have been invested in the studies of field emission from 0D nanoparticles [1,2], 1D nanotube [3,4] or nanowires [5], and 2D graphene [6].…”

Zinc oxide (ZnO) nanomaterials have attracted considerable scientific interest due to their promising potential in extensive applications, such as nanolasers, light-emitting diodes, photovoltaic devices, and gas sensors. In this paper, the research focused mainly on geometric effects, emission stability, and ambient insensitivity of ZnO nanomaterials. We report the field emission and emission-stimulated desorption of ZnO nanomaterials, which makes it possible to use them as field emitter cathodes in harsh environments with fluctuating pressure.
