Mössbauer Spectroscopy: Recent Developments

Abstract

In this review I have emphasized two basic points. First, Mössbauer spectroscopy has been widely used as a tool for basic research in solid-state physics, chemical structure, and magnetism. Second, the technique has been applied to many analytical and materials science problems where the nature of the sample prevents the use of more traditional approaches. Mössbauer spectroscopy research on frozen solutions, colloids, interface chemistry, and crystallographic transformations can be expected to increase rapidly in the next few years.

Examination of the metallization behaviour of an ABS surface

“…Accordingly, the sub-micrometer thickness of the sensitized surface and identification of the oxidation procedure of Sn and its stability was determined by Mössbauer spectroscopy which is based on the Mössbauer effect depicted in Figure 2. As a result, corresponding spectra imply that all Sn 2+ oxidize to Sn 4+ succeeding the submersion to an activation blend [41] which is analogue to our observation. The electroless Ni plating was applied with a NaPH 2 O 2 reduction agent.…”

“…After Pd immersion, normalSn2+ ions are oxidized and normalPd2+ ions are reduced on the surface as presented in Figure 2. Connected to this observation, the sensitized thickness was examined in detail in Cohen's study [41,42]. Accordingly, the sub-micrometer thickness of the sensitized surface and identification of the oxidation procedure of Sn and its stability was determined by Mössbauer spectroscopy which is based on the Mössbauer effect depicted in Figure 2.…”

First principles calculation of Mössbauer isomer shift

“…The use of synchrotron ␥-radiation in nuclear resonance scattering spectroscopies [17][18][19][20][21][22][23] [17][18][19][20][21][22][23][24]) is that it is capable to provide information on the local electronic structure and chemical bonding on an atomic scale. Therefore, Mössbauer spectroscopy finds a large and increasing number of applications for the study of not only crystalline solids, but also of biological systems [11,12], molecules isolated in inert gas matrices [25][26][27][28][29][30][31][32][33], disordered solids [34][35][36], etc. The range of applications of Mössbauer spectroscopy varies from traditional solid-state physics and chemistry to biochemistry [11,12], nano-science [13] and materials science [8,34], to metallurgy [14,15] and even to space exploration studies [16].…”

Characterization of Metal‐zeolite Composite Catalysts: Determining the Environment of the Active Phase

“…Although in situ Mössbauer spectroscopy is a useful technique for determining the active phase and oxidation state of Fe in metal‐zeolite composite catalysts, the technique is limited by the small number of conveniently applicable Mössbauer isotopes ( 57 Fe, 119 Sn for transmission studies and 57 Co for emission spectroscopy) . As most zeolite‐based catalysts may not use these common Mössbauer elements (Fe and Sn), this technique can only be considered a complementary technique to X‐ray absorption spectroscopy, XPS and UV‐Vis.…”
