X-ray absorption spectroscopy of Mn/Co/TiO2 Fischer-Tropsch catalysts: Relationships between preparation method, molecular structure, and catalyst performance
Article Abstract:
A detailed characterization study of a series of Mn-promoted Co/TiO2 Fischer-Tropsch (FT) catalysts, synthesized by various methods with the aim of obtaining different manganese locations at the catalyst surface is presented. Results reveal that after calcination the catalysts are composed of Co3O4 particles and a MnO2 phase, and association is clearly enhanced by the homogeneous deposition precipitation method.

Synchrotron radiation effects on catalytic systems as probed with a combined in-situ UV-vis/XAFS spectroscopic setup
Article Abstract:
The synchrotron radiation effect on aqueous homogenous copper solutions was investigated using UV-vis spectroscopy in a combined in-situ UV-vis/XAFS spectroscopic setup. Two different systems were studied for this purpose, which includes a copper bipyridine-catalysed oxidation of benzyl alcohol to benzaldehyde with 2,2,6,6-tetramethylpiperidinyl-1-oxy and base as cocatalysts.

Highly mixed phases in ball-milled Cu/ZnO catalysts: An EXAFS and XANES study
Article Abstract:
New highly mixed phases are identified in Cu/ZnO systems by EXAFS and XANES at both the Cu and Zn K-edge. The formation of highly mixed [Cu.sub.1-x][Zn.sub.x]O phase has indicated strong Cu/Zn interaction in the Cu/ZnO system, suggesting the presence of highly mixed phases in conveniently prepared activated catalysts.
