%T PENGARUH VARIASI WAKTU PIROLISIS TERHADAP MORFOLOGI CNT (CARBON NANOTUBE) BERBASIS KARBON AKTIF TEMPURUNG KELAPA
%X The study of the effect of pyrolysis time variation on the morphology of CNT
(Carbon Nanotube) based coconut shell has been successfully performed. Used
coconut shell which is a natural material because Indonesia is the third largest
coconut producer after Philippines and India according to Central Bureau of
Statistics. The aim of this research is to study the process of CNT synthesis using
CVD (Chemical Vapor Deposition) method with variation of pyrolysis time of 2
hours, 4 hours, 6 hours and to know the result of CNT characterization formed
from variation of pyrolysis time . Synthesis of CNT is done by reacting coconut
shell activated coconut, ferrocene (Fe (C5H5) 2) as catalyst and benzene as carbon
source with gas argon (Ar). Purification CNT using a solution of nitric acid
(HNO3) 65%. Result of characterization of XRD and SEM pyrolysis time
variation showed 2 hours result 2 hours = 23,29 ° and particle size 238,09 nm,
when 4 hours got 2θ = 23,55 ° and particle size 52,91 nm, when 6 hour got 2θ =
23.49 ° and particle size 190.77 nm. The conclusions of this study indicate that at
4 hours pyrolysis time obtained morphology CNT with the smallest diameter of
52.91 nm.
