| 英文摘要 | rhodium- and iron phosphate-based catalysts are by far the most promising catalysts for oxy-bromination of methane (obm) reaction. however, most literature reported either rh- or fepo4-based catalysts, and the results were rarely studied in a uniform environmental condition. in this report, comparative study was conducted on silica- and silicon carbide-supported rhodium and iron phosphate catalysts with the main focuses on stability performance and coke deposition. the catalytic results demonstrated that the stability of both rh- and fepo4-based catalysts was greatly influenced by the supports used, and silicon carbide-supported catalysts showed much better anti-coking ability as compared with silica-supported ones. temperature-programmed oxidation over the used catalysts further indicated that the coke formation mechanisms were completely different between silica-supported rhodium and iron phosphate catalysts. while cokes might be caused by condensation of ch2br2 over supported iron phosphate, methane decomposition might be the reason for coke formation over silica-supported rhodium catalyst. these findings might pave the way for designing highly efficient and stable catalysts of the obm reaction. |
