Abstract
The surface structures of supported Ru catalysts derived from Ru3(CO)12/γ-Al2O3 and Ru3(CO)12/SiO2 during the preparation procedures were studied mainly by EXAFS (Extended X-ray Absorption Fine Structure) analyses and also by IR and UV/VIS Diffuse Reflectance spectroscopies. A direct evidence was found for bonding feature in metal-support interaction, which explains the large difference in surface structures and catalysis of the Ru species supported on γ-Al2O3 and SiO2.Keywords
