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
Advanced Materials Letters,
2012, Volume 3, Issue 4, Pages 309-314
AbstractAl(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 o C 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.
