TY - JOUR ID - 705149 AU - Jašek, Ondřej - Eliáš, Marek - Zajíčková, Lenka - Kučerová, Zuzana - Matějková, Jiřina - Rek, Antonín - Buršík, Jiří PY - 2006 TI - Carbon nanostructures synthesis in microwave plasma torch at atmospheric pressure PB - Masaryk University CY - Brno SN - 802104070X KW - carbon nanostructures KW - atmospheric pressure KW - microwave discharge KW - electron microscopy N2 - We have successfully synthesized CNTs in microwave plasma torch at atmospheric pressure from the mixture of methane, hydrogen and argon. The plasma torch was generated at the frequency of 2.45 GHz using an iron hollow electrode. Argon (1000 sccm) was flowing through the electrode whereas methane (10-40 sccm) and hydrogen (100-400 sccm) were added to the expanding torch from outside. The CNTs were grown on substrates placed at various distances from the torch electrode. The substrates were silicon wafers(10x15 mm) with deposited 200 nm thick silicon oxide layer and thin layer (5-20 nm) of iron catalyst on the top. The samples were imaged by scanning electron microscopy(SEM) and transmission electron microscopy(TEM). The processes in the discharge were monitored by optical emission spectroscopy(OES). The SEM analysis showed presence of well aligned 50 micrometer long multi-wall CNTs with narrow diameter distribution centered around 20 nm. Except the carbon nanotubes the layers often contained various carbon and carbon/iron structures. ER -
