求助催化剂部分英文翻译,急,急,急!?A family of Fe-containing SBA-15 silica synthesized by a simple one-pot hydrothermal method was synthesized and tested in the hydrogen sulfide partial oxidation for sulfur production at 200 ?C and atmospheric pressure. All these materials maintain the porous hexagonal structure of SBA-15 showing agood chemical and mechanical stability. Isolated Fe3+ species are mainly observed at high Si/Fe ratio (ca.40). However, extra framework iron oligomers and/or aggregated iron oxide clusters are mainly observed for samples with Si/Fe ratio lower than 10. High H2S conversion and high selectivity to sulfur (higher than99%), with very low selectivity to SO2 (lower than 0.5% at H2S conversion between 60 and 80%), have been achieved. Moreover, the TOF decreases when increasing the amount of iron in the catalysts.:29 ]查看更多6个回答 . 9人已关注
