Structure And Catalytic Activity Relationships Of Fe/Co Supported On Different Sources Of Al(OH)3 in The Production Of Multiwall Carbon Nanotubes By Catalytic Chemical Vapour Deposition Method 

H. Kathyayini and N. Nagaraju

Volume 3, Issue 4, Page 309-314 | DOI: 10.5185/amlett.2011.8291

Keywords: Catalysts; multiwall carbon nanotubes; supports; catalytic chemical vapor deposition.

Abstract: 

Al(OH)3 from different sources has been used as supports for a mixture of Fe/Co salts and employed in the synthesis of Multiwall Carbon nanotubes by Catalytic Chemical Vapour Deposition method. These supported-catalysts have been characterized by Scanning Electron Microscopy, Powdered X-ray diffraction, and Thermo gravimetric studies. Surface area was determined by N2 adsorption technique. Carbon nanotubes synthesis reactions have been conducted at 700 oC using acetylene as the hydrocarbon source in N2 atmosphere. The quality and quantity of Multiwall carbon nanotubes depend not only on the carbon source, the textural & structural properties of the support and also their interactions with the active components available on the surface.  Copyright © 2012 VBRI Press.
