STUDI PENGARUH JENIS DAN KOMPOSISI KATALIS PADA PROSES PERTUMBUHAN CARBON NANOTUBE (CNT) DENGAN METODE CATALYTIC CHEMICAL VAPOUR DEPOSITION (CCVD)

Abstract

Abstract

Carbon nanotube is one of the nanotechnology that applicated in a variety of science such as electronics, chemistry and etc. In this research staked with system Catalytic Chemical Vapour Deposition (CCVD) process to syntheses Carbon nanotubes from acetylene gas using Co/Al₂O₃ and Fe/Al₂O₃ catalysts with catalyst heavy 0,3 gram,operation temperature 700^oC, flow rate rasio of N₂ and acetylene gas is 1 : 1. From analysis result by Scanning Electron Microscopy (SEM), CNT was formed MWNT type with difference diameter, where in order to larger active component concentration resultant diameter of CNT larger. Whereas product severe sintheses result turn inside out collating with active component. The larger of active component, product weight syntheses result smaller. For Fe/Al₂O₃ catalyst was given CNT diameter larger compared with CNT syntheses used Co/Al₂O₃. catalysts.
