Abstract. In this work, we have synthesized carbon nanotubes (CNT) using different biohydrocarbon precursors namely palm, olive, coconut, corn and sesame oils. Prior to the synthesis process, thermogravimetric analysis (TGA) characterization was performed on the carbon precursors to facilitate the optimization procedures of CNT and reach maximum yield and higher quality CNT.The CNT arrays were deposited on a silicon substrate by thermal catalytic decomposition of the precursor using 5.33 wt% ferrocene. The synthesis was carried out at 750 °C for 60 min under argon ambient. The samples were characterized using field emission scanning electron microscopy, microRaman spectroscopy and TGA analysis. The difference in oil density resulted in different quality and Nano HybridsOnline -08-22 ISSN: 2234-9871, Vol. 2, pp 43-63 doi:10.4028/www.scientific.net/NH.2.43 © 2012 This is an open access article under the CC-BY 4.0 license (https://creativecommons.org/licenses/by/4.0/) tube diameter of CNT produced. Among all, the CNT synthesized from coconut oil can be considered as the best bio-hydrocarbon precursor for higher quality (I D /I G ~0.62) and good purity (81.95 %) CNT.

“…GO as the initial material for rGO production was synthesized by electrochemical exfoliation utilizing hyper-branched TC14 surfactant, which also has been proven in previous reports to give better performance as compared to commercial sodium dodecyl sulphate (SDS) surfactant [9][10][11]42,43]. Meanwhile, the MWCNTs were synthesized by a modified thermal CVD (TCVD) method utilizing waste cooking palm oil as the carbon source [44][45][46][47][48][49][50][51]. The TC14-rGO_MWCNTs hybrid film was then coated with a 10 nm layer of thin Pt NPs to further increase the surface area of the fabricated CE film.…”

“…Recently, we reported the use of WEO for the production of another carbon material namely CNTs [21] and amorphous Al-Cu alloy nanowires decorated with CS [22]. The use of waste [23][24][25][26][27] and natural precursors [28][29][30][31][32][33][34][35][36] to produce carbon materials may not only be beneficial for nanotechnology research field but also preserve the environmental sustainability at the same time. The CS were synthesised using thermal chemical vapour deposition (TCVD) method while the ZnO were synthesised using the sol-gel method.…”

Zinc oxide (ZnO)/carbon spheres (CS) nanocomposites were successfully synthesised using waste engine oil as precursor for the CS production. ZnO nanorods were grown using sol-gel immersion method with MgZnO as the seeded catalyst and thermal chemical vapour deposition was used to synthesise CS. Different configurations of ZnO/CS structures were prepared i.e. CScoated ZnO and ZnO-coated CS. The structures of composite samples were analysed using field emission scanning electron microscopy (FESEM), Energy-Dispersive X-ray (EDX), micro-Raman and X-ray Diffraction Spectroscopy (XRD). FESEM observations revealed the structural changes of pristine ZnO and CS in composite structures. The as-present of ZnO or CS was believed to affect the subsequent growth of another structure. Field electron emission (FEE) properties of both nanocomposites were also investigated. It was found that ZnO-coated CS sample has better FEE properties with lower turn-on (3.48 Vµm-1) and threshold field (6.35 Vµm-1) obtained at current density of 0.1 and 1 µAcm-2 , respectively. This study highlighted that nanocomposites of ZnO and CS have successfully enhanced the field emission performances of materials compared with pristine ZnO or CS due to the structural changes of material emitter.
