Gold/titania interfaces and their role in carbon monoxide oxidation
Article Abstract:
A study was conducted to analyze the synergistic interplay between the constituents in gold/titania catalysts utilized in low-temperature carbon monoxide oxidation. The chemisorption characteristics of various prepared model gold/titania surfaces were utilized to carry out the analysis. Results indicated a mechanistic framework for carbon monoxide oxidation based on oxygen adsorption on vacancy sites of titania and carbon monoxide adsorption on gold.

In situ extended X-ray absorption fine structure study during selective alcohol oxidation over Pd/[Al.sub.2][O.sub.3] in supercritical carbon dioxide
Article Abstract:
High-pressure in situ X-ray absorption near-edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) data are described during the selective oxidation of benzyl alcohol to benzaldehyde in supercritical carbon dioxide over a Pd/[Al.sub.2][O.sub.3] catalyst. The results obtained are in accordance with simulations of the XANES data using the FEFF8.20 code and EXAFS data fitting/simulation.
