Abstract

Carbon nanotubes were prepared by thermal chemical vapor deposition (TCVD) method using Ti02 as a catalyst and palm oil as a precursor. TiC«2 solution was prepared by using sol-gel method and then spin coating technique was used to deposit Ti02 solution onto Silicon substrate. The synthesis temperatures were varied with various temperatures; (600-850°C). The carbon nanotubes sample was characterized by using Raman Spectroscopy and Field Emission Scanning Electron Microscope (FESEM). The result show that the CNTs were grows at 750°C in bamboo like CNTs structure. Minimal amount of CNTs were detected at 800°C sample. There are no CNTs were noticed at temperature lower than 750°C. At higher temperature, higher than 800°C a-c carbon were found. The Raman shift of D and G band are between 1325cm"1 and 1630cm'1. Meanwhile the IJ/IG at 750°C is 1.13 and 800°C is 1.06. The intensity ratio was increases when temperature decreasing. As a conclusion, CNTs grow at temperature of 750°C and 800°C.
