Structure of aluminum, iron, and other heteroatoms in zeolites by X-ray absorption spectroscopy
Autor: Jeroen A. van Bokhoven, Carlo Lamberti
Heteroatoms in zeolites provide them their catalytic activity. The silicon atom is always tetrahedrally coordinated and its valence IV, those of the heteroatoms much more varied. This is further complicated by the easy removal of heteroatoms out of t

The present status of in-situ scanning transmission X-ray microscopy (STXM) is reviewed, with an emphasis on the abilities of the STXM technique in comparison with electron microscopy. The experimental aspects and interpretation of X-ray absorption s

Geometric and electronic structure of alpha-oxygen sites in Mn-ZSM-5 zeolites
Autor: Radu, Daniel, Glatzel, Pieter, Gloter, Alexandre, Stephan, Odile, Weckhuysen, Bert M., de Groot, Frank M. F.
It is shown that alpha-oxygen sites are generated by the decomposition of N2O in ion-exchanged Mn-ZSM-5 zeolites. The catalytic activity decreases to zero in 1 h, and the amount of alpha-oxygen that is formed is reduced from similar to 30% alpha-oxyg

The valence and local symmetry of iron in framework-substituted FeZSM-5 with a high Fe dilution (Si/Fe = 360) was studied by means of Kbeta-detected X-ray absorption spectroscopy. This technique combines high-resolution (DeltaE similar to1 eV) fluore

The structure of the iron species in mildly calcined over-exchanged Fe/ZSM5, prepared by CVD of FeCl3, was studied during heat treatments in He or O-2/He (50:50) by coupling in situ Fe K edge HR-XANES and EXAFS. The majority of iron appears to be pre
