IMPREGNATION OF IRON CATALYST ONTO CARBON NANOFEBERS

This report outlines the background of the project "Impregnation of Iron Catalyst
onto Carbon Nanofibers". Application of carbon nanofilaments which are carbon
nanotubes (CNTs) and carbon nanofibers (CNFs) in catalyst field has attracted great
interest from scientist due to their excellent properties. In this experimental work,
CNFs was used as catalyst support for iron catalyst due to its outstanding property
that enabled it to be great catalyst support. The CNFs was synthesized by Chemical
Vapor Deposition (CVD) technique and the iron oxide was deposited by incipient
wetness impregnation. The composite were analysed by scanning electron
microscopy (SEM) for surface morphology, X-ray Diflractometer (XRD) for the
crystalline structure and Brynauer Emmet Taylor (BET) analysis to determine it
surface area and pore volume. Iron catalyst been impregnated by incipent wetness
impregnation using a ferric solution of nickel nitrate. Then, the solution been
filtered, washed and dried to get the iron supported CNF in powder form. After
purification, the powder been analysedby XRDand field emission scanningelectron
microscopy (Fe-SEM) together with Energy Dispersive X-Ray (EDX) analysis. A
number of samples were prepared by manipulating the concentration of ferric
solution of nickel nitrate andthe residence time during impregnation.
