Summary: The metals commonly used as catalysts for the synthesis of carbon nanotubes (CNTs) through chemical vapor deposition (CVD) are copper (Cu) and nickel (Ni). These metals are chosen due to their differing properties and mechanisms that facilitate the growth of CNTs.
Explanation:
Copper (Cu): Copper is used as a catalyst in CVD due to its low carbon solubility. This property leads to a surface growth mechanism where the graphene or CNTs form directly on the surface of the copper at high temperatures. The high temperature is necessary to decompose the hydrocarbon precursors, which then deposit on the copper surface to form the nanotubes. This mechanism is advantageous as it allows for precise control over the growth location and can lead to high-quality, single-layer graphene or CNTs.
Nickel (Ni): Nickel, on the other hand, has a high carbon solubility. This characteristic results in a different growth mechanism known as surface segregation/precipitation. In this process, carbon atoms diffuse into the bulk of the nickel foil at high temperatures. During the cooling process, the carbon segregates and precipitates out of the nickel, forming graphene sheets or CNTs on the surface of the metal. This mechanism can lead to the formation of multilayer structures and is often used when thicker or more robust structures are desired.
Both copper and nickel are effective catalysts for CNT synthesis due to their ability to facilitate the decomposition of hydrocarbon precursors and the subsequent growth of carbon structures. The choice between these metals often depends on the specific requirements of the application, such as the desired thickness, quality, and uniformity of the CNTs.

The growth mechanism of graphene is primarily influenced by the type of metal catalyst used, with copper (Cu) and nickel (Ni) being the most common. Cu, with its low carbon solubility, facilitates a surface growth mechanism where graphene forms at high temperatures on the Cu surface through hydrocarbon decomposition. Conversely, Ni, due to its high carbon solubility, enables a mechanism involving surface segregation and precipitation. In this case, carbon diffuses into the bulk Ni at high temperatures and segregates upon cooling, leading to the formation of graphene sheets on the metal surface.
Surface Growth on Cu: The growth of graphene on Cu involves a process where hydrocarbons decompose at high temperatures, releasing carbon atoms that then assemble on the Cu surface. This mechanism is favored because Cu does not readily dissolve carbon, forcing the carbon to remain on the surface and form graphene. The growth is typically a two-dimensional process, where carbon species add to the edges of growing graphene islands, eventually coalescing into a continuous monolayer. Once a complete layer is formed, the surface becomes less reactive, inhibiting further growth of additional layers.
Segregation and Precipitation on Ni: In contrast, the growth mechanism on Ni is more complex due to its ability to dissolve carbon. During high-temperature synthesis, carbon atoms diffuse into the Ni bulk. As the system cools, these carbon atoms segregate and precipitate out of the Ni, forming graphene layers on the surface. This process is influenced by the cooling rate and the initial carbon concentration in the Ni, which can affect the number and quality of graphene layers produced.
Influence of Synthesis Conditions: The nucleation and growth of graphene are highly dependent on various synthesis conditions such as temperature, pressure, precursor flux and composition, and the properties of the catalyst including its crystallinity, composition, crystal facet, and surface roughness. These factors can significantly influence the shape, orientation, crystallinity, nucleation density, defect density, and evolution of the graphene crystals.
Research and Development: Research into graphene growth mechanisms has been extensive, with studies focusing on optimizing conditions for single-layer graphene production. Techniques such as vapor-trapping have been developed to synthesize large-grain, single-crystalline graphene, demonstrating the importance of local environmental conditions in the growth process. Additionally, modeling and simulation tools like COMSOL Multiphysics have been used to better understand and predict the growth mechanisms under different conditions.
In summary, the growth mechanism of graphene is a complex interplay of the catalyst's properties and the synthesis conditions.
