PROMOTING EFFECT OF TIN OXIDE ON THE ACTIVITY OF SILICA- SUPPORTED GOLD CATALYSTS USED IN CO OXIDATION
In this study various Au/SnOx-SiO2 Catalysts were prepared and tested in CO oxidation. It was found that the addition of tin oxide onto silica increased significantly the activity of Au/SiO2 catalysts due to the alteration of the nanoenvironrnent of gold, which was evidenced by XPS and FTIR measurements.
