ABSTRACT:

A primary objective of this work is to characterize the stable, catalytically active surface formed on supported iron catalysts during Fischer-Tropsch synthesis. The characterization will be based on a comparison of Auger electron spectroscopy and x-ray photoelectron spectroscopy (XPS) measurements on the catalysts with measurements from standard iron compounds which comprise the various chemical states of iron that may be present on the catalyst surface. Efforts during this period, August 1, 1983 to December 31, 1983 have involved XPS measurements on clean and oxidized iron foils and on bulk Fe sub 2 O sub 3 and Fe sub 3 O sub 4 powder samples. The goal of these measurements has been to characterize the surface chemistry of these standard materials and to obtain standard iron XPS and Auger spectra. (ERA citation 09:009537)
