Analysis of Raman Spectroscopy and SEM of Carbon Nanotubes Obtain by CVD

Study by SEM of Carbon Nanotubes Deposited by CVD Using Al2O3 and TiO2 as Catalysts

“…When the catalysts were obtained, they were poured in another crucible to sinter in an Argon inert atmosphere at 730ºC for 11 minutes with a constant flow of 500 L/min, then ethylene was supplied at 300 L/min both gases for 30 minutes, after the time the valve of C2H4 is closed, lowering the Argon supply to a flow of 300 L/min for 120 minutes upon reaching 25°C. [2], [3]. The nanotubes were dispersed in a beaker with 20 ml of isopropanol by ultrasound for 9 minutes.…”
