Abstract

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.
