Surface topography of synthesized graphene from green carbon source using thermal chemical vapor deposition

The graphite oxide has been a common carbon source to synthesis graphene layers [1-3]. In this study, palm oil has been proposed as one of the green carbon source available and environment friendly. The double furnace CVD method was used to synthesis graphene layers [4]. The nickel sheet was used as a substrate and palm oil act as carbon feedstock to supply carbon atom. The substrate and carbon source were placed in two different furnaces. The carbon source furnace and the substrate furnace were heated to 300°C and range from 850°C to 1100°C consecutively. The argon was used as carrier gas to carry the carbon atom towards the substrate. The both furnaces were switch off after several time synthesis times for cooling process. The Atomic Force Microscopy, UV-VIS Spectroscopy, FTIR spectroscopy and Raman spectroscopy was used to characterize the as-synthesized graphene.
