Preparation and characterization of CNTs from palm oil by floated catalyst method / Faizudin Zuberi

Carbon nanotubes exist as a macro-molecule of carbon, analagous to a sheet of graphite rolled into a cylinder. Multi Walled Nanotubes (MWNTs) can be considered as a collection of concentric SWNTs with different diameters. Carbon Nanotubes (CNTs) are produced by using Floated Catalyst Thermal Chemical Vapor Deposition by using palm oil as precursor and ZnO catalyst. The CNTs were prepared at 5 different deposition temperature. The raman spectroscopy reveal that existence of MWNTs in samples. Thermogravimetric analysis (TGA) results showed that 90% purity was achieved at the expense of 2% weight catalyst material.
