| 英文摘要 | The chemical looping oxidative dehydrogenation (CL-ODH) of ethane represents a highly effective approach for converting ethane into the value-added product ethylene. This investigation focused on the synthesis of SrMnO(3 )and its halide ions doped derivatives (SrMnO3Cl and SrMnO3Br) through the sol-gel method. The performance of these perovskites, employed as oxygen carriers in CL-ODH of ethane, was explored. The results unveiled several advantageous outcomes arising from the incorporation of halide ions (Cl- and Br-) with larger radius into the oxygen sites of the SrMnO3 perovskite. Halide ions doping notably induced cell volume expansion and enhanced lattice fringe spacing. Furthermore, it contributed to elevated oxygen vacancy concentration, increased Mn4+/Mn3+ molar ratio, and improved oxygen ions mobility within the bulk lattice. Fixed-bed experiments demonstrated that these redox catalysts, doped with halide ions, exhibited outstanding activity and stability during cycling tests, exhibiting enhanced both ethylene selectivity and yield in CL-ODH of ethane. In summary, the introduction of halide ions into SrMnO3 emerges as a promising strategy for enhancing the performance of CL-ODH in ethane conversion for SrMnO3 based oxygen carriers.(c) 2023 Society of Chemical Industry and John Wiley & Sons, Ltd. |
