Chemical vapor deposition (CVD) is the most effective method for the synthesis of large-scale and high-quality graphene. However, the growth temperature of graphene is high, about 1000 掳C, using conventional CVD, meaning that it is expensiveand thus limits the use of the material. The ...
Graphene is an advanced carbon functional material with inherent unique properties that make it suitable for a wide range of applications. It can be synthesized through either the top–down approach involving delamination of graphitic materials or the bo
Chemical vapor deposition (CVD), a well-known and controllable method to prepare thin films, has attracted significant attention for the synthesis of large-area, uniform graphene samples. Nonetheless, significant efforts are still needed to improve our fundamental understanding of the graphene growth ...

For the chemical vapor deposition (CVD) of graphene, the grain growth of the catalyst metal and thereby surface roughening are unavoidable during the high temperature annealing for the graphene synthesis. Considering that nanoscale wrinkles and poor uniformity of synthesized graphene originate from the ...
Although scalable graphene could be grown on metal substrates by chemical vapor deposition(CVD) method, as-grown graphene needs to be transferred onto a dielectric layer for further devices construction. The direct synthesis of graphene on dielectric substrates could avoid the damages and contaminations...
Chemical oxidation method, also known as oxidation cutting method, is a very widely used method, in which carbon bonds of graphene, GO or carbon nanotubes are usually destroyed by H2SO4, HNO3or other oxidants [39,40,41,42,43]. Liu et al. [44] developed an experimental system, which use...
Raman spectra and mapping images were used for characterization of the films. It was found that nearly 95% of the Raman spectra show a hallmark of monolayer/bilayer graphene. The transport properties of the films were investigated with Hall measurements....
We report the synthesis of graphene bubbles by CVD method using metal supported (iron, copper and bimetallic iron/copper) mesoporous MCM-41 catalysts. Growth of graphene bubbles was achieved using isobutane gas as the carbon source at the temperature of 900掳C. The metal doped MCM-41 shows a...
A cost-effective, simple and non-hazardous route for synthesis of few-layered graphene from waste zinc carbon battery (ZCB) electrodes via electrochemical expansion (ECE) has been reported. In this synthesis, we have electrochemically exfoliated the graphene layers, by intercalating sodium dodecyl benz...
