Title: Structural studies on iron-based exhaust gas catalysts by means of X-ray absorption spectroscopy
Abstract:X-ray absorption near-edge structure (XANES) and pre-edge spectroscopy of supported iron oxide catalysts showed that the state of the catalytic sites varies between Fe2+ and Fe3+ without altering the ...X-ray absorption near-edge structure (XANES) and pre-edge spectroscopy of supported iron oxide catalysts showed that the state of the catalytic sites varies between Fe2+ and Fe3+ without altering the number of nearest oxygen neighbours. The preferential location of Fe at the octahedral lattice sites of gamma-Al2O3 was verified by extended X-ray absorption fine structure (EXAFS). Valence-to-core X-ray emission spectroscopy (V2C-XES) gave new insight into intermediate species during catalytic deNOx.Read More
