Structural properties of graphene from green carbon source via Thermal Chemical Vapour Deposition (CVD)

The most common carbon source is graphite oxide in synthesis the graphene layers. This study proposed palm oil as the best new source as a carbon feedstock which is more cheaper, green and bio-renewable resources. The palm oil was placed in the first furnace (precursor furnace) and the 2 cm x 2 cm Nickel seeded substrate was placed in the second furnace (deposition furnace). The furnaces were heated to 450 degrees C and range from 1000 degrees C to 1100 degrees C for first and second furnaces consecutively. Argon gas acted as carrier gas to carry the carbon atom towards the Nickel substrate. After several minutes synthesis time, both furnaces were switched off for cooling process. The as-synthesized graphene was characterized in confirming its properties using Atomic Force Microscopy and Raman Spectrometer. Raman spectra show that D peak appears at similar to 1345 cm(-1) and G peak appears at similar to 1595 cm-1. From the results, it shows that palm oil is the one of the most promising renewable natural carbon sources available to synthesize the graphene.
