Coordination and Oxidation States of Iron Incorporated in Mesoporous MCM41sbauer spectroscopies. Both Fe(II) and Fe(III) located in low coordination states in top layers of pore walls exhibit Lewis acidity and may participate in Fe(III) ? Fe(II) processes at low temperatures (570 K). Furthermore, Fe(III) ? Fe(II) cycles can be achieved and repeated with participation of t

Iron Uniform-Size Nanoparticles Dispersed on MCM-41 Used as Hydrocarbon Synthesis Catalysthe solids were characterized by M?ssbauer spectroscopy, X-ray diffraction, BET, TGA, CO chemisorption and volumetric oxidation. Although the catalyst showed a high CO conversion when it was used in the hydrocarbon synthesis from CO and H. (14.3% at 1 h of reaction time) mainly methane was formed. Th

Characterization of Supported Gold Catalysts with 197Au M?ssbauer Effect Spectroscopyange in the relative weight of the spectral contribution of the surface atoms. The presence of ionic gold in active gold catalysts is not observed. The spectra can be interpreted in terms of bulk-like contributions from the inner-core atoms plus contributions from the outermost atoms at the surface

,,Fe M?ssbauer Investigation of Solid-State Redox Reactions of Lithium Insertion Electrodes for Advaum insertion materials containing iron. Our . M?ssbauer technique was successfully applied to the determination as to which transition metal ion was a redox center in the insertion electrodes, such as LiFe.Mn.O., LiFeTiO., or LiFe.Ni.O., for the lithium-ion batteries.

Iron Halide Species Produced by Laser-Evaporation matrices to obtain their M?ssbauer spectra. Iron fluoride (Fe.F., FeF. and Fe.F.) and iron iodide (Fel. and Fe.I.) were produced by the reaction of laser-evaporated iron atoms with sulfur hexafluoride SF. and methyl iodide CH.I, respectively. The yields of the products varied depending on the conce
