“…In contrast to gaseous carbon sources, liquid [6a,22] and solid carbon sources [23] such as ethanol, [16,24] methyl formate (C 2 H 4 O 2 ), [9,25] diethylamine, [26] methyl metacrylate (PMMA), [27] camphor (C 10 H 16 O), [28] and fullerene soot powders [29] have also be utilized for the graphene growth by MPCVD. Rincon et al [24a] synthesized graphene by MPCVD using evaporated ethanol carried by Ar flow as the carbon source at atmospheric pressure, without utilizing metal catalyst or adding external flow of H 2 .…”

“…At low temperatures, camphor was also shown to have a stronger decomposition capability than traditional carbon source such as methane. Wang et al [29] synthesized vertical graphene films using fullerene soot powder on Ni foil by MPCVD. A mixture gas of H 2 (20 sccm) and Ar (20 sccm) were used to generated plasma at a pressure of 30 Pa under 1.2 kW microwave irradiation.…”

Advances in Microwave‐Enhanced Chemical Vapor Deposition for Graphene Synthesis

Graphene has received intensive research interest in various areas due to its outstanding mechanical, electrical properties, high specific surface area and 2D flexible structure. Mechanical exfoliation generates defect-free graphene, but suffers from ultra-low yield. This drawback can be partially overcome by chemical vapor deposition method (CVD). However, conventional CVD imposes high temperature. In recent years, microwave plasma-enhanced CVD (MPCVD) has been widely investigated as a viable strategy toward large-area graphene synthesis. In this review, important issues during the process are summarized. Firstly, various MPCVD devices that have been explored for graphene synthesis are presented. Secondly, effect of carbon sources, nitrogen-containing gases, and CO 2 in the precursors are discussed. Thirdly, MPCVD enabled direct synthesis of graphene on metal substrates and non-metal sustrates is discussed. Finally, the advances of MPCVD in lowering the graphene synthesis temperature are demonstrated.

“…It is well-known that graphene nanolayers can be derived from graphite [ 55 , 56 , 57 , 58 ], and that graphite can be made from graphene [ 59 ]. Graphene can also be synthesized from fullerene [ 60 , 61 , 62 ]. Furthermore, fullerene can be exfoliated to form an atomic-scale 2-D polymeric network [ 63 ].…”

The Transformation of 0-D Carbon Dots into 1-, 2- and 3-D Carbon Allotropes: A Minireview

Carbon dots (CDs) represent a relatively new type of carbon allotrope with a 0-D structure and with nanoparticle sizes < 10 nm. A large number of research articles have been published on the synthesis, characteristics, mechanisms and applications of this carbon allotrope. Many of these articles have also shown that CDs can be synthesized from “bottom-up” and “top-down” methods. The “top-down” methods are dominated by the breaking down of large carbon structures such as fullerene, graphene, carbon black and carbon nanotubes into the CDs. What is less known is that CDs also have the potential to be used as carbon substrates for the synthesis of larger carbon structures such as 1-D carbon nanotubes, 2-D or 3-D graphene-based nanosheets and 3-D porous carbon frameworks. Herein, we present a review of the synthesis strategies used to convert the 0-D carbons into these higher-dimensional carbons. The methods involve the use of catalysts or thermal procedures to generate the larger structures. The surface functional groups on the CDs, typically containing nitrogen and oxygen, appear to be important in the process of creating the larger carbon structures that typically are formed via the generation of covalent bonds. The CD building blocks can also ‘aggregate’ to form so called supra-CDs. The mechanism for the formation of the structures made from CDs, the physical properties of the CDs and their applications (for example in energy devices and as reagents for use in medicinal fields) will also be discussed. We hope that this review will serve to provide valuable insights into this area of CD research and a novel viewpoint on the exploration of CDs.

Recent advances in the growth of carbon nanowalls (CNWs) and vertical graphene nanosheets using various plasma‐enhanced chemical vapor deposition methods are reviewed in this paper. Growth methods are classified into hot‐ and cold‐wall reactors equipped with diverse plasma generation systems, and their respective characteristics are summarized, with particular attention to the behavior of reactive species, such as ions and radicals, generated within the plasma. Recent progress in this research domain is outlined for each method, and an organized account of the chemical kinetic phenomena occurring within the plasma is provided. Finally, future perspectives are discussed. Fundamental data are obtained through real‐time in situ measurements of ions and radicals, and the construction of a database from these data offers microscopic insights that significantly enhance processing outcomes for macroscopically controlling the mechanical shapes and chemical properties of CNWs.This article is protected by copyright.
