PENGARUH KOMPOSISI FERROCENE-BENZENA PADA SINTESIS CARBON NANOTUBES (CNT) DENGAN METODE SPRAY PYROLYSIS

Abstract

Study of effect of ferrocene-benzena composition in carbon nanotubes synthesis has successfully been carried out using spray pyrolysis method. In this work, the benzene was employed as a carbon source and the ferrocene was applied as a catalyst on the temperature of 900 oC by using the furnace for 30 minute. The produce carbon nanotubes was weighted using analytic balance and subsequently characterized by Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDS). The result shows that the number of produced carbon nanotubes increased with increasing the composition of ferrocene-benzena, for the composition of 0,03 g/ml, 0,06 g/ml and 0,09 g/ml the masses of CNT are 1,53 gram, 2,19 gram and 2,45 gram, respectively. The analysis using SEM shows that the diameter of CNT increased in length with increasing the composition of ferrocene-benzena, for the composition of 0,03 g/ml, 0,06 g/ml and 0,09 g/ml the diameter of of CNT are 50 ± 2 nm, 80 ±1nm and 92 ± 2 nm, consecutively. The analytical result using EDS shows that the amount of carbon contents for the composition of 0,03 g/ml, 0,06 g/ml and 0,09 g/ml are 89,56 %, 85,68 % and 85,67 %, respectively. The ratio of Fe and C for each the composition are 0,03, 0,05 and 0,08. The best composition of ferrocene-benzena was obtained using the composition of 0,06 g/ml.
