“…The intensity of the 2D band is lower than that of the G band with the I G /I 2D ratio around 2.45. This means that the obtained graphene is multilayered rather than single-layered, and the layer number is around 5-10 [24]. By contrast, although the Raman spectrum of region 2 displays a similar I G /I 2D ratio as that of region 1 , a characteristic peak at 1350 cm −1 corresponding to a defect/disorder induced D band is found.…”

Abstract:Graphene was first fabricated on the surface of an electroless Ni-P coating/carbon steel (Ni-P-G) to improve its corrosion resistance. Meanwhile, an electroless Ni-P coating (Ni-P) was heated (Ni-P-H) under the same condition as Ni-P-G for comparison. The morphological results showed that a wavy multilayer graphene was formed on the surface of Ni-P-G. The layer number of the graphene film was 5-10 according to the analysis of Raman spectra and observation by a high-resolution transmission electron microscope. The I D /I G ratio calculated from the Raman spectrum revealed that the graphene growing at the grain of Ni-P-H had larger grain size than that growing at the grain boundary. The electrochemical results showed a higher R p , a lower CPE dl , and a lower corrosion rate of Ni-P-G than Q235 steel, Ni-P, and Ni-P-H, indicating a higher corrosion resistance. In addition, the surface potential map achieved by a scanning Kelvin probe presented a more positive surface potential of Ni-P-G than Ni-P with the difference being around 375-750 mV, demonstrating a lower corrosion tendency of Ni-P-G.

“…Ozawa et al 27 used transition metal complexes including nickelocene during the combustion of benzene and reported higher fullerene yield in soot when additives were used. Prikhod'ko et al 28 used catalytic substrates with copper and nickel in the flame zone of premixed propane-oxygen and found nickel substrates to be more efficient for graphene growth. By controlling the angle of orientation amorphous soot was also observed on the nickel substrate.…”

“…It is indicated that the formation of graphene layers on the substrate occurs vertically along the flame height, with subsequent changeover to a soot structure. It is displayed that the minimum number of graphene layers (two or three) is observed at angles of inclination of the substrate relative to the vertical axis of the flame within 0°-30° [4].…”

For two decades and beyond, remarkable progress has been made in the use of chemical vapour deposition methods for comprehending 2D materials growth. This review is aimed at providing an overview of several synthesis, characterizations and applications of large area graphene film on some substrates. First, the major growth methods are explained. Next, the mechanism of the graphene growth is discussed, focusing on reaction of precursors, diffusion of adatoms, energetics and kinetics of growth fronts, and effects of substrates. Then, the advantage of growing graphene film on some substrate over another is explained in some of the synthesis. Furthermore, the characterization of the various synthesized graphene films are explained, which suggests a suitable application to it.
