二氧化硅负载的含铁催化剂在 H2S 氧化中的催化性能与其通过 XPS 表征的表面组成相关。这使我们能够表明，二氧化硅负载的硫酸铁在硫生产中具有100%选择性的活性，而硫选择性的下降伴随着催化剂中二硫化铁相的出现。 (C) 2000 Elsevier Science B.V. 保留所有权利。
Catalytic properties of silica-supported Fe-containing catalysts in H2S oxidation have been correlated with their surface composition characterized by XPS. This allows us to show that iron sulfate supported on silica is active in sulfur production with 100% selectivity, whereas the decrease in selectivity to sulfur is accompanied by the appearance of iron disulfide phase in the catalyst.
