The SO2 oxidation catalysts, containing small amounts (0.01-0.03% mass) of platinum at the zirconia-promoted silica glass fibers (Pt-GFCs) demonstrate the relatively high activity at moderate temperatures (below 400C) and the appropriate thermal stability (up to 700C). The catalytic activity of Pt-GFC in the SO2 oxidation reaction is provided by the small, less than 1 nm, partially charged platinum clusters, while platinum in a form of large metal particles is practically inactive. Pt-GFCs have the high (up to ~20 mass %) sorption capacity with respect to SO2. Such sorption occurs via the interaction of SO2 with oxygen, either present in the gaseous reaction mixture or pre-adsorbed in the fresh GFC structure, with the possible formation of the intermediate sulfates in the glass bulk of the catalyst. Besides, Pt-GFC may effectively oxidize CO in the presence of significant amounts of sulfur dioxide.
