Abstract
Catalytic properties of silica-supported Fe-containing catalysts in H2S oxi dation have been correlated with their surface composition characterized by XPS. This allows us to show that iron sulfate supported on silica is activ e in sulfur production with 100% selectivity, whereas the decrease in selec tivity to sulfur is accompanied by the appearance of iron disulfide phase i n the catalyst.
