Abstract

For the first time, vertically aligned carbon nanotubes (VACNTs) have been successfully synthesized using waste chicken fat as the starting material. Chicken fat oil, which was obtained through a rendering process, was directly mixed with 5.33wt% ferrocene as a catalyst to form the synthesis stock. A mixture of single- and multi-walled VACNTs was synthesized at a fixed temperature of 750°C in a thermal chemical vapour deposition furnace. Field emission scanning electron microscopy, micro-Raman spectroscopy and thermogravimetric analyses showed that the produced VACNTs were of excellent quality, comparable to those obtained using conventional carbon sources, with a purity of 88.2% and tube diameters ranging from 18 to 78nm. Based on our study, waste chicken fat is a promising carbon source for the synthesis of high-quality and high-purity VACNTs.
