What Is Mössbauer Spectroscopy and Its Applications in Catalysis?
Mössbauer spectroscopy relies on the resonant absorption and emission of gamma rays by atomic nuclei, specifically iron-57 and other Mössbauer isotopes. This technique is highly sensitive to small changes in the chemical and physical environment of the nuclei, making it ideal for studying the oxidation states, electronic structure, and coordination of metal centers in heterogeneous catalysts. Mössbauer spectroscopy can provide insights into the active sites and mechanisms of catalysis in materials like zeolites and metal oxides.
