Mossbauer characterizations

This contribution Is concerned with the magnetic and Mossbauer characterization of (a) Fe/zeollte (mordenlte) systems, and that of (b) Fe and/or Ru on boron-doped carbon substrates. Some correlations between the characterization and CO hydrogenation parameters will be pointed out. Because of limitations of space, we shall present salient features of these Investigations. At the outset. It would be befitting to present a succinct background on the basic principles of magnetic and Mossbauer characterization. [Pg.499]

High surface area carbon (CSX-203 desulfurized) was Impregnated with Fe3(C0)i2 and subsequently reduced at 723 K for 16 h In flowing H2 (30 cc/mln). The magnetic and Mossbauer characterization was carried out on the decarbonylated (fresh) and reduced products. [Pg.513]

Note that both the x-ray diffraction and Mossbauer characterization do not reveal the presence of phases other than Fe304 with the present statistics of the respective data sets. The presence of a very small amount of FeO(OH) is suggested in the electron diffraction pattern. It is not known whether FeO(OH) exists on the surface of the particles and/or as an independent particle to date. [Pg.124]
