| 摘 要： | 综述了氟化镁的合成、表征及在催化中的应用，指出了氟化镁在催化应用中的优缺点。氟化镁具有耐腐蚀性、高稳定性、表面性质可调等优点。目前主要应用的催化体系有：氟氯交换反应、氯氟烃的歧化反应、氯氟烃的加氢脱氯反应、加氢反应、加氢脱硫反应、氮氧化物的脱除等，在具有腐蚀性气体及反应介质的催化反应体系中具有独特的优势。缺点是氟化镁比表面积较小和表面酸性较弱，限制了其在催化研究中的应用。总结了高比表面积氟化镁及负载固体酸催化剂的制备方法及其在各类反应中的应用现状，重点阐述了高比表面积氟化镁的孔结构及其表面酸性的调控方法，最后指出了氟化镁催化剂在ODS替代物的合成领域及其它方面的发展前景。

| Abstract: | This review outlines the synthesis,characterization and catalytic application of MgF2(agnesium fluoride) based materials.The advantage and disadvantage are summarized.Such materials can be used in the systems involving corrosive gases and solvent due to its corrosion resistance and high stability.The catalytic reactions,are chlorine/fluorine exchange reactions,hydrogenation,hydrodechlorination of chlorofluorocarbon,hydrodesulfurization of organic compounds and removal of NOx.The catalytic application of magnesium fluoride itself is limited due to its low surface area and weak acidic properties.The recent development on the synthesis,catalytic application of MgF2 and supported solid acid catalysts is reviewed.Special attention is paid to the controlled synthesis of MgF2(magnesium fluoride) with high specific surface area and tunable acid-base properties.Finally,the importance of research on the preparation of high surface area MgF2 and its application prospects in catalysis is pointed out. |
