Effect of Carrier Gas on the Growth Rate, Growth Density, and Structure of Carbon Nanotubes
We attempt to understand the fundamental factors that determine the growth rate of carbon nanotubes. In a series of experiments on growing multiwall carbon nanotubes (MWNTs) by thermal chemical vapor deposition, we found that the addition of carrier gas and the type of carrier gas can change the growth rate, growth density, and structures of MWNTs. We explain these results based on the dissocia...
متن کاملNumerical Analysis of Inlet Gas-Mixture Flow Rate Effects on Carbon Nanotube Growth Rate
The growth rate and uniformity of Carbon Nano Tubes (CNTs) based on Chemical Vapor Deposition (CVD) technique is investigated by using a numerical model. In this reactor, inlet gas mixture, including xylene as carbon source and mixture of argon and hydrogen as carrier gas enters into a horizontal CVD reactor at atmospheric pressure. Based on the gas phase and surface reactions, released carbon...
متن کاملEvaluation of the Effect of Ni-Co NPs for the Effective Growth of Carbon Nanotubes by TCVD System
A systematic study was conducted to understand the influences of catalyst combination as Ni-Co NPs on carbon nanotubes (CNTs) grown by Chemical Vapor Deposition (TCVD). The DC-sputtering system was used to prepare Co and Ni-Co thin films on silicon substrate. Ni- Co nanoparticles were used as metal catalyst for growing carbon nanotubes from acetylene (C2H2) gas in 850 ̊ C during 15 min. Carb...

متن کاملEvaluation of catalyst ball-milling process on growth and diameter of carbon nanotubes on iron nanoparticles
In this study, we describe the growth of carbon nanotubes on commercial iron nanoparticles without carbon shell (Fe (nm), size 2O3 and Fe* (nm)/MgO) was carried out by mixing commercial Fe* nanoparticles (as catalyst) with Al2O3 and MgO powders (as supports)by using ball-milling method. The results show in spite of the fact that ball-milling process can have neg...
